[wix-users] Manual uninstall

[Vanniekerk, Tyrel (GE Healthcare)]

Seems they retired the cleanup util.  I did fine another fix utility.  I will give that a try.  Would still be nice to understand all of it better.

You can use the Windows Installer Cleanup Utility to remove all the MSI related data for the hidden msi.

Hi,

Is there a resource out there that explains how the registry keys fit together for the WiX Toolset Bootstrapper and in my case, I have an internal hidden MSI install as well.

I accidentally removed a custom action I was still using and that caused the uninstall to fail.  Is there a way to force remove all the remnants of the installer?  I normally manually delete certain registry keys, but of course that leaves thousands of entries created by the MSI.

A tool that already does this would be nice, but I would like to understand the relationship between the registry keys/Guids of the bootstrapper down to the internal MSI down to all the MSI's bits and pieces.

Thanks,
Tyrel
