How to force uninstall of broken Wix bundle

I've built a WiX bundle with a custom Managed Bootstrapper Application to play around with it and didn't realize that I had to implement logic for uninstall.

Now I have a version of the bundle installed which cannot be uninstalled.

Is there a clean way to remove this bundle? I've tried to locate the cached bundle .exe in the C:\ProgramData\Package Cache folder and replace it with a fixed version but unfortunately that still doesn't actually uninstall and it doesn't remove the entry from the installed programs view in Control Panel.

When I examine the MSI log file for the updated bundle, during unistallation, I see some lines that ream something like this:

Revo Uninstaller Pro was able to uninstall all of my bugged bundles yet (it has 30-day trial).
