Sometimes it is necessary to manually delete leftover extension files and delete the cache

Remove leftover extension files

  1. Close SSMS completely
  2. Open Windows Explorer and navigate to one of these locations:  
    • SSMS 21: C:\Program Files\Microsoft SQL Server Management Studio 21\Release\Common7\IDE\Extensions\
    • SSMS 22: C:\Program Files\Microsoft SQL Server Management Studio 22\Release\Common7\IDE\Extensions\
  3. Look for a folder containing SQLinForm* files and delete it (Note: The folder name is a random string like ul4254xk.zre)
  4. Please check also these folders:
    • SSMS 21: %LocalAppData%\Microsoft\SSMS\21.0_*\Extensions\
    • SSMS 22: %LocalAppData%\Microsoft\SSMS\22.0_*\Extensions\

Rebuild the extension cache

  1. Open a Command Prompt as Administrator
  2. Run the following command:
    • SSMS 21:
      "C:\Program Files\Microsoft SQL Server Management Studio 21\Release\Common7\IDE\ssms.exe" /setup
    • SSMS 22:
      "C:\Program Files\Microsoft SQL Server Management Studio 22\Release\Common7\IDE\ssms.exe" /setup
  3. Wait for the command to complete (no window will open, it takes usually 1 second)
  4. Start SSMS normally

Troubleshooting

Problem: „Package could not be loaded“ error message

If you see an error message like „The ‚SQLinFormVSIXPackage‘ package did not load correctly“ after uninstalling, some cached data may still remain. Follow these steps as explained above.

Problem: SSMS freezes or becomes unresponsive

If SSMS freezes after installing SQLinForm:

  1. End SSMS using Task Manager
  2. Uninstall SQLinForm using the Visual Studio Installer (see above)
  3. If problems persist, clear the cache as described above
  4. Download and install the latest version of SQLinForm

Problem: Menu entries remain after uninstallation

If SQLinForm menu entries are still visible after uninstallation:

  1. Follow the troubleshooting steps above to remove leftover files
  2. Run the ssms.exe /setup command to rebuild the cache

Extension Folder Locations

The SQLinForm extension files are located in one of the following locations:

  • SSMS 21: %LocalAppData%\Microsoft\SSMS\21.0_*\Extensions\[random-folder]\
  • SSMS 22: %LocalAppData%\Microsoft\SSMS\22.0_*\Extensions\[random-folder]\

These folders may also contain Extension files:

  • SSMS 21: C:\Program Files\Microsoft SQL Server Management Studio 21\Release\Common7\IDE\Extensions\[random-folder]\
  • SSMS 22: C:\Program Files\Microsoft SQL Server Management Studio 22\Release\Common7\IDE\Extensions\[random-folder]\

Note:

  • The * represents a hash value that may vary between installations (e.g., 4e68b3d8)
  • The [random-folder] is a randomly generated name like ul4254xk.zre
  • Look for the folder containing SQLinForm* files to identify the correct one to delete
