Error when trying to uninstall an application: Error opening installation log file. Verify that the specified location exists and is writable
Original product version: Windows 10 - all editions
Original KB number: 2564571
When you attempt to uninstall any product in "Programs and Features", a new "Windows Installer" window appears and gives the following error:
Error opening installation log file. Verify that the specified location exists and is writable.
This issue occurs if Windows Installer Logging is enabled, but the Windows Installer engine can't properly write the uninstallation log file. This condition occurs if the Windows Installer's application heap becomes freed and loses the information on where to store the log file. When this occurs, Windows Installer attempts to write to the location C:\Windows\System32 and addresses it as a file. Proper behavior would be to write to the following location and file name: C:\Users\<username>\AppData\Local\Temp\MSIxxxxxx.log.
Microsoft has confirmed this to be a problem in the operating systems listed in the Applies To section of this article.
To work around this issue, stop and restart the Explorer.exe process using Task Manager.
