Error 1001 on uninstall

Question

Error 1001. An exception occurred while uninstalling. This exception will be ignored and the uninstall will continue. However, the application might not be fully uninstalled after the uninstall is complete

I can't uninstall or install the application. This particular box is not able to access the internet and I don't have physical access so most of the googleable results are not useful since they suggest running an exe from Microsoft.

What are the manual steps to resolving this issues. There is no way I can physically reach this machine nor does there seem to be a way for me to get files onto it. This is code that I'm developing and testing. I've tried repair and remove which fails out. I've scoured the registry but I must be missing something here.

If this is better on SuperUsers I'll gladly move it.

Answer 1

I had the same uninstall issue removing an application that I wrote that includes two Windows Services, ergo custom actions were unavoidable. I solved it be running PC Tools Registry Mechanic. Unfortunately, Symantec has retired that product. However, Microsoft Fixit has been known to help with registry related problems. http://support.microsoft.com/mats/Program_Install_and_Uninstall
