Hi Screamer,
you have identified an issue!
Under Word 2003, make sure that from the Menu: Tools --> Options --> Macro Security --> 'Trusted Publishers' tab --> 'Trust all installed add-ins and templates' is set to true. If not set, the add-in will not run. You can set this after installation.
For Word 2007, under 'Word Options' --> 'Trust Center' --> 'Trust Center Settings' , make sure:
- 'Add-ins' --> 'Disable all Application Add-ins (may impair functionality)' is NOT set
I haven't found the 'Trust all installed add-ins' equivalent in 2007, and I have not been able to replicate your problem in 2007, so hopefully that is enough... but it might be hidden somewhere in all the options. Let me know if this solves your problems.
Which version of Word and Windows are you using?
Cheers,
Andrew
