[wix-users] Unable to Uninstall a Patch

[Hoover, Jacob]

Same version of Windows Installer on both OS’s?  Have you used procmon to see the parameters being passed to msiexec? Are you using a bundle, or just pure MSI/MSP’s?  Does specifying the log file rectify the situation?

Hi Jacob,

This issue is happening in Windows 7, but working fine in Windows 10. Any thoughts?

So when trying to remove it from the command line add a logging path that is valid..Ex: /L*V "%TEMP%\MyPatchUninstall.log"

Somewhere something is trying to change the default logging to be “wix” which is obviously not a valid path/file…

Sorry. Actually, there is a message which shows "Error opening installation log file. verify that the specified location exists and is writable wix."

A better definition of "not able to uninstall" is needed.  Do you have logs from the attempted patch removal?

Subject: [wix-users] Unable to Uninstall a Patch

I am working on a Patch sample using the following link. However, I am not able to uninstall the patch either from Control Panel or from the command line MSIEXEC /i "MsiPath" MSIPATCHREMOVE="PathToMSP"

http://petermarcu.blogspot.in/2007/06/wix-building-patch-using-new-patch_29.html

Can anyone please let me know how to successfully uninstall or rollback a patch?
Note: I have set the AllowRemoval attribute to "yes" in the Patch.wxs file for the Patch element.

Regards,
Venkatesh
