Hi!

I've implemented an automation add-in in C#, targeting Excel XP. My
installer adds an "OPEN"-entry to HKEY_CURRENT_USER\Software\Microsoft
\Office\10.0\Excel\Options, and this works fine.

However, my customer wants to install the add-in for all users. I've
been trying to change my installer to write to HKEY_LOCAL_MACHINE
\SOFTWARE\Microsoft\Office\10.0\Excel\Options instead, but Excel XP
doesn't seem to look at that subkey.

Any ideas?

Thanks!
