I have been working on several plugins for office. One for Word, one for excel.

They are working fine on the developer system however when I try to install the Word plugin on any other machine it doesn't appear to register with Word at all. It isn't listed in the com add-ins in word.

It is listed in the registry under add-ins (HK_CURRENT_USER area), it does appear in add/remove software and I can not find any indication of why it wouldn't be loading.

The excel plugin (which uses some of the same code) does install and work without issues.

Any suggestions on where to look would be appreciated.

Thanks
