The standard interface gets boring over time. Therefore, users are looking for an alternative to stock skins and turn to the services of third-party launchers. But behind a beautiful interface, there is often unoptimized code that leads to errors. So let's take a look at what Launcher 3 is and how to fix application errors.
About the program
It is a graphical system shell that includes the desktop, menus, widgets, icons, lock screen, etc. Each of these elements can be fine-tuned "for yourself".
Some Chinese-made smartphones use Launcher 3 as standard, so removing it or force stopping it will cause more serious problems. 
Errors in Launcher 3 occur due to failures in the process of exchanging packet data, which, although they are restored after a while, are pretty annoying by the frequent appearance on the smartphone screen. Those. the problem is more cosmetic than a serious glitch in the device's operating system.
How do I fix the application error?
After digging through the mobile forums, I found many ways to work around the ill-fated error. Some users solved the problem drastically: resetting the device to factory settings or performing a full flashing of the smartphone. I do not agree with the opinion of the members of the forum, tk. the above methods should only be used as a last resort.
And I will present an easy and quick way that does not entail deleting user files and resetting the settings:
- Disconnect your phone and remove the battery.
- After a minute, assemble the device and turn it on.
- Go to "Settings" - "Applications" - "All".
- Find Launcher 3 and tap on it.
- Stop the application and click on the "Storage" item.
- In the window that opens, click on "Delete data" and "Clear cache".
If you installed the application yourself and want to uninstall it, then after completing the fourth step, click the "Remove" button and confirm the operation.
After these steps, the error will no longer be displayed on the smartphone screen, but this does not guarantee that it will not appear in the future. Therefore, it is recommended to install another shell, for example
Sometimes launcher.exe and other EXE system errors can be related to problems in the Windows registry. Several programs can share the same launcher.exe file, but when these programs are uninstalled or changed, sometimes orphaned (invalid) EXE registry entries are left behind.
Basically, this means that while the actual path to the file may have changed, its incorrect former location is still recorded in the Windows registry. When Windows tries looking up these incorrect file references (file locations on your PC), launcher.exe errors can occur. In addition, malware infection may have corrupted the registry entries associated with Microsoft Works and Microsoft Money 99 Basic. Thus, these invalid EXE registry entries need to be repaired to fix the root of the problem.
Manually editing the Windows registry to remove invalid launcher.exe keys is not recommended unless you are PC service professional. Errors made while editing the registry can cause your PC to malfunction and cause irreparable damage to your operating system. In fact, even a single comma in the wrong place can prevent your computer from booting!
Because of this risk, we highly recommend using a trusted registry cleaner such as %% product %% (Developed by Microsoft Gold Certified Partner) to scan and repair any launcher.exe-related registry problems. Using a registry cleaner automates the process of finding invalid registry entries, missing file references (like the one causing your launcher.exe error), and broken links within the registry. Before each scan, a backup is automatically created, allowing you to undo any changes with one click and protecting you from possible damage to your computer. The best part is that fixing registry errors can dramatically improve system speed and performance.
Warning: Unless you are an experienced PC user, we do NOT recommend manually editing the Windows Registry. Incorrect use of Registry Editor can lead to serious problems and require you to reinstall Windows. We do not guarantee that problems resulting from improper use of Registry Editor can be corrected. Your use of the Registry Editor is at your own risk.
To manually repair your Windows registry, first you need to create a backup by exporting a portion of the registry related to launcher.exe (eg. Microsoft Works and Microsoft Money 99 Basic):
- Click on the button To begin.
- Enter " command" v search bar ... DO NOT PRESS YET ENTER!
- Holding the keys CTRL-Shift on the keyboard, press ENTER.
- A dialog box for access will be displayed.
- Click on Yes.
- The black box opens with a blinking cursor.
- Enter " regedit" and press ENTER.
- In the Registry Editor, select the launcher.exe-related key (eg.Microsoft Works and Microsoft Money 99 Basic) you want to back up.
- On the menu File choose Export.
- In the list Save to select the folder where you want to save the Microsoft Works and Microsoft Money 99 Basic backup key.
- In field File name type a name for your backup file such as "Microsoft Works and Microsoft Money 99 Basic Backup".
- Make sure in the box Export range value selected Selected branch.
- Click on Save.
- The file will be saved with the extension .reg.
- You now have a backup of your launcher.exe-related registry entry.
The next steps for manually editing the registry will not be described in this article, as they can most likely damage your system. If you would like more information on manually editing the registry, please see the links below.

- Find the item "Launcher 3" and select "Delete".
It is worth noting that this does not always work for a simple reason, the specified item cannot be found. The fact is that sometimes the shell has a different name. You should also check, probably among the list there is Launcher, Trebuchet, Desktop - all this is the name of the same application.
You don't have to use the shell at all, then the standard Android design will appear.
Download the programs from the link from the store https://play.google.com/store/apps/details?id=com.actionlauncher.playstore&hl=ru.
Installation is performed by means of a standard launch of the installation file. It is likely that the user will not want to risk it again by installing the same program, then you can choose any other. A more complete list can be found in the store by entering the word Launcher.
Clearing the program
Like many other applications, this one accumulates information about its work as cookies and cache. It is likely that the error is in this place, so it is necessary to clean up the garbage and check the functionality of the shell. For cleaning you should:
- Tap on the item "Settings";
- Then select "Applications";
- Go to the All tab to find Launcher 3;
- Open the shell details;
- You should delete the cache, along with it and the cookies, stop the application.
Often these actions are enough and the smartphone will no longer send error notifications, but there are cases when the specified procedures cannot be performed due to a complete system freeze.
Reset
As a last resort, you can resort to. The procedure will delete all data and provide a clean operating system, in the form in which it was released from the factory. This is necessary if the smartphone completely freezes after starting or restarts randomly. Sometimes absolutely any action provokes a mistake, you will have to take drastic measures.
This function is built into the smartphone, but the procedure for entering the menu may be slightly different:
- You need to simultaneously hold down the Power button and the volume up control, sometimes the Home button is used;
- Select "Wipe data / Factory reset";
- Confirm the procedure.
At this, the error with the Launcher should be completely eliminated and not appear again. In some cases, there is a resumption of the problem after a short period of time, then it is better to replace the shell. In general, the application is quite convenient, economical, fast and beautiful, therefore it deserves a right to exist.

Launcher 3 an error occurred on Android, what to do? Launcher 3 is a custom skin that is quite common on Android devices. A number of Chinese-made smartphone models use it as standard and come pre-installed. Some users install Launcher 3 for Android smartphone on their own as an alternative shell, and for that they have their own good reasons:
- Nice interface;
- Simplicity and ease of customization;

The launcher allows you to add and structure folders, create a set of icons and widgets on each table, customize animation and select a background image to your liking. It is even possible to use a conductor, albeit somewhat non-standard.
Interestingly, the wide popularity of Launcher 3 is explained not so much by its advantages as by a specific error that occurs very often with this application. Failure occurs during the exchange of packet data and in itself does not pose any threat to their security and the operation of the device as a whole.
The external manifestation of the problem looks like the message "" appearing on the screen when you change the desktop, go to another menu, or try to open Google Search. Another option for visual manifestation is icons that are broken or not displayed at all on the screen.
If all this does not lead to an emergency termination of the explorer, which is extremely rare, then the Launcher 3 error can be considered an annoying external interference, since even the icons after a while are restored on their own. But this problem tends to occur more and more often, so it's worth knowing how to fix the Launcher 3 error.

Due to such troubles, the launcher application may not open correctly and give an error. To get started, don't panic, just try restarting your device.

Software conflict
If the problem appeared after installing an application, even if it was taken from the Market, it may make sense to try to remove it. Why could this situation have happened? There are several reasons, but the main one is the halt in the development of one of the applications. This happens when developers stop a project, and their applications remain in the public domain.
Factory settings

This can be done in two ways - through settings or recovery.
Even a child can master the first method. To implement it, you need to enter the menu and the "Recovery" section. There is a button we need to reset all settings to the factory settings. Everything will have to be installed and configured again. Be aware that everything that was saved in the device's memory will also be deleted, including photos, SMS messages and numbers.
Recovery
This method is suitable for more advanced users. In each device, the entrance to the recovery takes place in a different way. But in most cases, this is pressing several keys at the same time, for example, the power button and the volume rocker. In order to find out exactly how your gadget goes into this mode, just type the name of the model of your gadget into the Internet and add the word "recovery". Next, the search engine will give you the most suitable options.
Once in the desired mode, you need to select the wipe data \ factory setting item with the volume buttons and confirm your choice with the power key. All gadget settings will be reset to factory settings.
