I wrote and installed a small VBdotNet application on several user machines.  
During an update installation, the uninstall phase failed, triggering an
error.  The error indicates that the uninstaller is attempting to remove a
registry key which has no connection to the application.  I’m guessing that
the key was modified during the installation and therefore logged as part of
the installation.

How do I remove the instruction to delete that registry key?  Is there a log
somewhere that I can find and edit?  This was done with the standard dotnet
setup package.

This same application has been installed and uninstaled repeatedly on other
user PCs, so I know it isn’t anything to do with the application itself.
