Windows Installer Help

Method 11: Check Your System for One or More Pending Installations

Warning: The steps discussed below require you to work with the Windows registry. You must be very careful while editing the registry because there is no undo option in Registry Editor and any mistakes in registry edits may render your PC unbootable. This is the reason why, it is recommended that you back up the registry before you make any edits to it

Steps to clean up information related to pending installations

1. Open Start menu, select Run, in the Open box type regedit, and then click the OK button.
2. In the Registry Editor window, navigate to the following registry key:
   
   HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\InProgress
   
   
3. Remove all information from the InProgress key.
4. Repeat the process for the following registry key:
   
   HKLM\System\CurrentControlSet\Control\SessionManager\PendingFileRenameOperations
   
   
5. Restart your computer and run the installation of the program that caused the problem again.
