- Platforms: Windows 2008 Server, Windows 7, Windows 8, Windows XP, Windows Server 2012, Windows Vista, Windows 10
- Java versions: 7.0, 8.0
Note... To install Java, you must have Windows administrator rights on your computer.
It is recommended that you turn off the firewall before beginning installation over the Internet. In some cases, the default firewall settings prohibit any unattended installations or installations over the Internet (such as installing Java over the Internet). If the firewall is not configured appropriately, it can block the download / installation of Java in some cases. For instructions on disabling the firewall, see the documentation for the firewall.
- Go to the download page manually
- Click the button Windows Online
- The File Download dialog box opens, prompting you to execute or save the download file.
- Click the button to run the installer. Run(Run).
- To save the file for installation to be done later, click Save.
Select the folder location and save the file to your local system.
Clue. Save the file to your computer, such as your desktop.
Double click on the saved file to start the installation process.
Detection of obsolete versions (8u20 and later)... Starting with Java 8 Update 20 (8u20), on Windows systems, the Java Uninstall Tool integrates with the installer. This allows you to remove obsolete Java versions from the system. This change applies to 32-bit and 64-bit Windows platforms.
Java shutdown and request recovery notifications
The installer notifies the user if Java content is disabled in web browsers and provides instructions on how to enable it. If the user has previously hidden some security prompts for Java Web Start applets and applications, the installer provides an option to restore those prompts. The installer may prompt you to restart the computer if the user has previously denied the request to restart the Internet browser.
People who have just installed a brand new operating system on their computer or laptop often come across a message on the Internet like "You need to install Java to work correctly." For inexperienced users, this message can be terrifying and confusing. But don't panic, you've come to the right place. This article will analyze in detail the question of why the presented software is needed, and what to do if Java is not installed. Also, detailed installation instructions will be posted for both Windows users and Linux Ubuntu "users".
What is Java?
The message about the need to install software is most often encountered by people who have recently installed a new operating system. It appears on the Internet when you try to open a page or launch an application. From this we can conclude that it is necessary to run programs written in this language. Yes! Java is a programming language and it's all over the place. Nowadays, almost all sites use this language in their code, and by the way, it was created back in 1995 and there are still no analogues of its level. This is because it is constantly being updated and improved. Because of which, in turn, it is the best in terms of information processing speed, it has incredibly reliable protection and it is very reliable.
This language is used not only on personal computers, it is ubiquitous. It was used both in game consoles and in supercomputers. Therefore, its necessity becomes clear.
So, we figured out the concept, now we need to move on to the main question - what to do if Java is not installed?
Java won't install on Windows
If you do not have Java software on Windows, then you urgently need to install it. You can do this by visiting the official website of the application. But it also happens that you downloaded the program, and for some reason it refuses to be installed on your PC. Now we will analyze the reasons and tell you what to do if Java is not installed on Windows 7.
So, let's look at a common problem. The fact is that Java is downloaded from the official site as a web installer. That is, after this download and and opening the downloaded file launcher via connection to and load the Internet necessary files and place them in library, from Why Java will work. But this is in the optimistic version, it happens that the download and installation of the program is blocked by antiviruses, believing that the action being executed threatens the system. There are two ways out of this situation. The first means disabling all antiviruses. The second one is more trivial, you can simply download an offline installer on the website. Its size is about 50 MB.
It may also be that the installation of a new version of Java is interfered with by the previous one. To solve this problem, go through the control panel to the "Programs and Features", and there in the list find Java and uninstall it, and then repeat the installation.
In rare cases, viruses can do harm, so download an antivirus if you don't have one and check for them.
Registry errors can also block Java from being installed, so download Cclaner or any similar program and clean your registry.
If none of the methods helped, visit the Java folder, which is located on the path C drive - ProgrammFiles - Java, and delete all files cleanly.
And as a last resort, go to Windows Update and update your operating system. Sometimes it helps.
Now you know what to do on Windows if Java is not installed. As you can see, there are a lot of options.
How do I install Java on Ubuntu?
Now we will talk about how Java is installed on the Ubuntu operating system.Various methods will be discussed. Linux users are well aware that installation is different on almost all distributions. oops programs can proceed in several ways. For everyone to find their own, we will illuminate them all.
Manual Java installation
The first method presented is suitable for users of GNU-based distributions.
Question: java is not installed, the installer does not start
Hello, there was a problem, java is not installed on Windows server 2008 Enterprise Service pack 2 64-bit.
After double clicking on the offline java installer, there is no reaction at all.
Neither jre-8u91-windows-x64.exe nor jre-8u91-windows-i586.exe - no reaction.
On the C: drive there is a folder C: \ Program Files (x86) \ Java \ jre1.8.0_51 \ with a folder structure inside (I don’t know, a full-fledged structure or some remnants, I attach a screen). But there is no java in the "control panel" and in the "add or remove programs" and in the "Start"!
Thanks in advance!
Answer: There is a web doctor on the server, look there
Question: Windows 7 Talking Installer: Create WinPE
Hello dear users and guests of the forum.
I am creating this topic in order to shed light on several important issues.
There is such a wonderful thing as Win PE.
It is a pre-installation windows system that is used by Windows 7 Installer.
Many people use it to create live cd with windows or for recovery tools.
The Windows 7 Automated Installation Kit (WAIK) lets you create, edit, and zip win pe images.
I read a lot about how to create your own assembly of windows pe and stuff the necessary programs there.
Actually the question itself:
I don't need to create a new win pe. You need to take the installation boot.wim and make it work.
It is necessary to put one portable program weighing 150 mb into it.
Who needs it?
I myself am a blind computer user. I have been using a computer for a long time, I live among the blind who also use a computer on windows 7.
To work on a computer, we use a screen reader or screen reader.
This program is called NVDA. This is a screen reader that reads all text from the screen with a voice.
Why is this needed?
One of the biggest problems for blind windows users is the inability to install the system on their own.
I install windows myself without any problems just because I see quite a bit and have already well remembered what and where it is. But many users are deprived of this opportunity, and if there was a way to modify the boot.wim file so that when the installer was loaded, this program was launched, all problems would be solved.
I myself tried to integrate sound drivers into boot.wim, but just turning on the sound was not enough.
At startup, the program will milk out an error. The message talked about some services.
I don’t know which way to dig.
If anyone decides to help me with this issue, it would be very good.
Answer: It's just building windows 7 with nvda.
I have it on my computer.
Nvda starts only after installing windows.
And there is a fully automated answer file.

Question: Windows XP won't install and start on an old laptop
Good and evil people are the last hope for you! An old laptop fell into my hands.
Parameters: intel pentium M processor 1600 mHz, 256 ram DDR 333 mHz, The monitor matrix is damaged, no floppy drive, no hard disk
When you connect the power and the monitor, the laptop starts up perfectly, the BIOS works, the settings are spinning in general, everything is as expected, but I can’t start or install the system from any media, neither from a hard drive, nor from a flash drive. During installation, the first stage passes, then a restart and a black screen with a "_" cursor. Win PE starts up with a bang. I tested the operative, hard drives and flash drives are all normal. I tried to install in all sophisticated ways, it did not help. Shil bios - to no avail.
Before the story: it all began that I got a Toshiba satellit l10 laptop in my hands. I decided for the sake of interest to start sowing ancient. Created a bootable PE flash. Launched and minted ten wondered that this pile of rubbish is still working. I decided not to leave it idle and screw it to it, that is, to make a video surveillance system out of it from bad neighbors and often passing olkash. Since there was no screw on it (IDE 2.5), and it is now rare to find it, I decided to put the system on a USB flash drive. After googling a lot and taking a break from a bunch of information, doing everything as expected, but at the second stage of the installation, he showed me a small flashing muzzle. I went ahead and installed it using another computer. on it the Windows from the flash drive started up with a bang. but inserting a USB flash drive into this beech came out the same. When the 1001st variant of beating against the wall came, I got tired of it and decided to solder the IDE 2.5 adapter to the IDE 3.5. Soldered, started hard, it seems, it works, it turns, everything makes noise as it should be. But here's how the system did not start and is not installed. It gets worse. Various installation options, programs, assemblies, nerves, red eyes have gone. In general, it all gradually grew from interest to principle. From all that happened to move a little further than the cursor, this was installed using WinNTsetup. There, after the blinking cursor, a message of the couple like "unmouted devise" appeared on a bright blue background.
Epilogue: everything works on other computers but not on it.
Huge prozba tell me what to smear with al nose poke. maybe it's just a matter of trifles, but I've already gone so deep that now you can't figure it out.
PS: loading the system stops at the moment after choosing the options for starting the system (safe mode, last successful, and so on ....) but none of the options starts the Windows mother. By listening to all the options.

Question: How to make an msi package from a Java installation package for installation via GPO
Good afternoon. Please do not kick me for this question. I am not familiar with JAVA. Explain to me or provide a link how to make an msi package from the JAVA installation package (jre-8u45-windows-i586.exe) for installation via GPO. Earlier, I extracted the contents from the exe-shnik and installed the update by running the msi file. Now it contains msi and another file LZMA_EXE, but if you run the installation, you get an installer error message. I suspect the solution is trivial. Tell me how can I solve this problem?
Sincerely,
Gennady.
Answer: no, the installation starts and fails with an error. Tried running in compatibility mode. Once java was installed, but I didn't understand why. More failed. So far I decided to install for users through the "run script at boot" policy:
Re-8u31-windows-i586.exe / s INSTALL_SILENT = 1 STATIC = 0 AUTO_UPDATE = 0 WEB_JAVA = 1 WEB_JAVA_SECURITY_LEVEL = H WEB_ANALYTICS = 0 SPONSORS = 0 EULA = 0 NOSTARTMENU = 1 REBOOT = 0
And wait for the next java service pack.
Well, start getting familiar with java. If a problem has arisen, it must be solved or understood.
Question: Can 64 and 32 bit java be installed at the same time?
Dear colleagues,
I have Windows server 2008 R2 64 bit, and now I need java 32bit in the server
64-bit java can you please tell me if I can install 64 and 32 bit java at the same time?

Question: java plugin not working in chrome
The problem is this: I put 7 sp1, I put chrome. I go to the page of my Internet bank (it uses Java), - says there is no plug-in, offers to download. Downloads, installs, after refreshing the page again says that there is no plugin and download again. I look in the chrome settings - there is no Java plugin. On java.com test page - says no plugin, test applet doesn't work. Okay, let's put it in full. Installed, the plugin appears in the chrome list. Now the applet is loaded, loaded, loaded .... And the message Error, click for details appears. I click, a window with the error "NullPointerException" appears. And such an error when loading any Java applet, either in the Internet bank or on the test page. At home, the system configuration is the same, though I installed it for a long time, but everything works as it should. Has anyone come across this?
Answer: The bitness of the browser and the bitness of the JAVA plugin must match. However, this may not be enough. It is known that for the Chrome browser version, like from 35 and higher, Google switched the standard interface for connecting plugins from NPAPI to PPAPI. But, fortunately, for a while we will be able to enable it manually using the special URL chrome: // flags / # enable-npapi This only works on Windows. For Linux, this possibility is already excluded. It is suggested to use Firefox instead. Instructions for installing JAVA plugin in Linux -
Question: Windows won't install and start after replacing the hard drive
Good day!
There is a laptop, HP Pavilion Sleekbook 15, I decided to change the hdd on it, tk. he is living out his last days and there is not enough space on it. The system (Windows 8.1) was installed on ssd, so I just pulled out the old hard one and installed a new one. I turn on the laptop - the error "MBR error 1 press any key to boot from floppy". When trying to reinstall Windows (since no manipulations in the BIOS, such as shutting down the secure boot and resetting the keys, did not help) in the disk selection menu, it gives an error "We could not create a new or find an existing partition" (when trying to install it both on ssd, and on the new hdd), but when you return the old disk, everything works fine, Windows is installed on ssd and loaded from it. What if, after installing Windows, just pull out the old disk and try to boot, then the laptop displays "Boot device not found. Please install an operating system on your hard disk". How? The system on a separate ssd is ...
Is there any way to solve this problem? I can't do without replacing hdd, the old reassigned sectors are already 40k after the impact)) How he still lives is also a mystery to me.
P.S. the new hdd is completely functional, the system, various software can see it well.
Answer: As a rule, the bootloader located on the SSD for the cache is not visible to the computer. Why dont know. On this occasion, we have already been. The most interesting thing is that it (the bootloader) tends to be installed first of all there ...

Owners of PCs with Windows XP, 7, 8 and 10 have the opportunity to use all the functionality of the Java software versions 7 and 8.
Java is installed in two steps:
- Download and install;
- Check how the installation went.
What is Java for?
Currently, without this application, it is no longer possible to imagine work in the global network. Java allows smartphones and a significant number of programs to work effectively: banking, navigation cards, games, etc. You should install only the current version of the application, which is a guarantee of the safety of the user's device.
Features of Java installation depending on the operating system
Oracle, the actual owner of this software, regularly invests in improving it. From the official website of "Oracle" you can download the current version of the application for all operating systems for free, for example, for such popular ones as Windows xp and 7.
There are two download modes available on their page:
- interactive;
- autonomous.
Prior to installation, you need to run xp and 7 and anti-virus utilities will prevent the installation of Java. Their protection needs to be temporarily suspended. After completing the installation, you can immediately enable them again to ensure active protection of your computer.
Installing Java in interactive mode provides for launching the IFTW executable file directly from the global network. Thus, the user must not disconnect the computer from the Internet until the process is complete. In the case of offline download, the "exe" file is downloaded first and then you can check it even without connecting to the network. Further, the configuration of Java in Windows xp and 7 is carried out in automatic mode, as well as the process of updating the utility.
In order to install on Windows xp and 7, the following requirements must be met:
- For installation, it is required to have administrator rights for Windows xp and 7 on a PC;
- It is required to use up-to-date versions of browsers.
Java is installed for 32 and 64 bit OS and browsers. For example, XP Home has only 32 bit. It is recommended that you select a software version that matches your OS and browser.
An important digression: Since today there is no longer any technical support from Microsoft Windows XP, the latest 8th Java will not function correctly in this OS.
How to find out the bitness?
To do this, open the "Help" or "About" tab in the browser, where the number of bits will be shown. If this is not indicated, then we can conclude that the browser is 32-bit.
It is recommended to use a 64 bit browser on powerful computers with a significant amount of RAM more than 4 Gb. This will allow the browser to use twice as much RAM, i.e. all applications will be able to function faster.
Performing a check
After completing the installation process, for any version of the download modes, you must restart the browser. Because it is needed to connect the Java module from the "Oracle" side. It is recommended to install only the latest versions of the program for maximum security.
Having problems installing or running Java
It is necessary to visit the official resource "Oracle", that is, the site "Http://www.java.com/ru/download/help/"... It provides free and constantly updated information on troubleshooting methods for installing and running the utility. For example, owners of computers with Windows XP, and there are a huge number of them, have file corruption problems. Microsoft has eliminated this problem by developing a special application "Microsoft Fix it" (works in XP and 7). You can install it for free from the Microsoft resource.
Java software is used as a platform for many Windows programs and is a recognized standard for the development of various applications and games. It provides a lot of opportunities for a programmer, and users have to pay for this in the form of the need to install Java libraries or even a Java Virtual Machine on a computer or laptop. And it would be fine everything went "without a hitch", but very often the JAVA software is not installed and an installation error is issued. What to do and how to successfully install it on a Windows system? Here are some tips.
1. Usually, when downloading software from the official site, you download a special web installer, which will then pull the necessary libraries by itself via an Internet connection. But here it can include an antivirus or a firewall in the game, which can regard this as viral activity and block access to the Internet for the installation application. Therefore, try to download a full-fledged offline installer from here - link, and then try to install Java through it. Don't be surprised that it weighs in at around 50 Megabytes, while the web installer is almost 50 times smaller. This is fine.
2. If you already had an older version of Java before, try uninstalling it and reinstalling it through the Windows Control Panel.
3. Check your Windows 7, 8 or 10 operating system with a good antivirus program. For instance, DrWeb CureIt or Kaspersky Antivirus... Very often, malware disguises itself as system libraries and then prevents them from being updated.
4. Clean the Windows registry using a special utility. For instance, CCleaner.
It is errors in the registry that are often the reason that Java software is not installed on a computer.
5. Try cleaning the system folders:
C: \ ProgramFiles \ Java
and
C: \ ProgramFiles \ Common Files \ Java
Sometimes files left over from old versions lead to Java installation error.
6. Try updating Windows components using Update Center. It may happen that the Java Runtime Environment installation error occurs even due to an outdated version of Internet Explorer.
7. Download the fix file with the fixes and apply the changes to the registry.
