Hello all;

I have a question about the proper way to uninstall my Excel Addin (.xla
file), developed with VSTO 2003.

My installer will remove the proper files and directorys, and I have a
custom command-line app which adjusts the .NET Configuration Security Policy
correctly (using caspol.exe).

What I want to know is how to keep Excel from trying to load the addin after
it has been uninstalled? Do I have to adjust the registry entry
"HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\ Excel\Options\OPEN", or is
there an easier/better way?
