Windows XP, outlook 2003, vsto 2005, C#
My add-in worked fine on dev and deployment machines for a while until I
clicked "Synchronize" button on the settings tab. After that none of the vsto
add-ins load on dev as well as deploy boxes. Unmanaged add-ins work fine. I
have done "SetSecurity" as well as running caspol command line (none of which
I really had to do on dev box before I ran into this issue). The debugger
shows that the addinloader.dll does not even load when I manually try to
enable the add-in from tools-options-other-... COM add-in dialog box.
