BlueStacks latest version already installed

5 quick methods to fix BlueStacks update issues

  1. Delete BlueStacks Registry Keys
  2. Delete Leftover BlueStacks Folders
  3. Clear the %Temp% Directory
  4. Uninstall BlueStacks With a Third-Party Uninstaller
  5. Open the Program Install and Uninstall Troubleshooter

BlueStack Systems released a new BlueStacks version in 2019. Thus, some users have uninstalled older versions of BlueStacks to update to the latest version. However, a “Latest version already installed” error message pops up for some users when trying to install BS 4.

A similar error message states, “Bluestacks is already installed on this machine.” Consequently, users can’t install the latest BS 4 Android emulator even when they’ve seemingly uninstalled the previous version.

The error message usually pops up when users have not thoroughly uninstalled the old BlueStacks version. Windows 10’s built-in uninstaller doesn’t always erase all registry entries and files for uninstalled software. This is how users can fix the “Latest version already installed” error message.

How to fix BlueStacks latest version errors?

1. Delete BlueStacks Registry Keys

BlueStacks’ “already installed” error messages can often be due to leftover registry entries. Users have confirmed that erasing leftover registry entries for BlueStacks can fix the “Latest version already installed” error. This is how users can erase those registry entries.

  1. Open Run by pressing the Windows key + R keyboard shortcut.
  2. Input ‘regedit’ in Run, and click the OK button.
  3. Next, open this registry path within the Registry Editor window:

2. Delete Leftover BlueStacks Folders

There might also be some leftover folders for BlueStacks. As such, check if there are remaining BlueStacks folders that need deleting. To do that, click the File Explorer button on the taskbar. Then enter these paths in File Explorer’s address bar:

  • C:\Program Files (x86)\BlueStacks
  • C:\ProgramData\BlueStacks
  • C:\ProgramData\BlueStacks\Setup

Delete any of those folders. Users can do that by right-clicking them in File Explorer and selecting Delete. Alternatively, select the folders and press the Delete button.


3. Clear the %Temp% Directory

There might also be some leftover BlueStacks files in the %Temp% folder. As such, some users might also need to clear that folder to fix the “Latest version already installed” error. This is how users can clear out the %Temp% folder in Windows 10.

  1. Open the Run accessory.
  2. Enter ‘%Temp%’ in the Open text box and click OK to open the %Temp% folder in File Explorer.

4. Uninstall BlueStacks With a Third-Party Uninstaller

As the “Latest version already installed” error is usually due to an incomplete removal of a previous version, uninstalling the software with a third-party uninstaller might fix the issue. Third-party uninstallers such as Revo Uninstaller erase all software registry entries and files. Then users don’t usually need to manually erase leftovers as outlined above.

Some users might wonder how they can uninstall BlueStacks with a third-party uninstaller when they’ve already removed the emulator! Users can roll Windows 10 back to a previous date with the System Restore tool. That will also restore the original BlueStacks software so long as users select a restore point that predates the date they uninstalled the Android emulator.

Then users can uninstall BlueStacks with a third-party uninstaller. This is how users can roll back Win 10 to a restore point.

5. Open the Program Install and Uninstall Troubleshooter

If users still can’t fix BlueStacks’ installation error, check out the Program Install and Uninstall troubleshooter for Windows 10. That troubleshooter repairs system errors which block software installing. Users can open the Program Install and Uninstall troubleshooter as follows.

  1. Click Download on the troubleshooter’s Windows Support page to download it.
  2. Then click MicrosoftProgram_Install_and_Uninstall.meta in the folder that includes the troubleshooter.
    program install and uninstall troubleshooter BlueStacks latest version already installed
  3. Users can click Advanced to select the Apply repairs automatically option.
  4. Press the Next button to initiate the troubleshooter.
  5. Then select the Installing option.
  6. Select BlueStacks as the program you’re trying to install if it’s listed. Select the Not Listed option if BlueStacks isn’t listed listed.
  7. Then click Next to go through the troubleshooter’s resolutions.

Those resolutions will probably fix the “Latest version already installed” error so that users can install BlueStacks 4. Try manually deleting the BlueStacks registry entries first as that resolution often fixes the “already installed” error.
