Since our MS-Office 2007 Add-In for SpiraTeam uses the Microsoft VSTO technology, it's limited to being installed for a single user on a given PC.However if you need to be able to have multiple users access it, there are some registry keys that you can manually add.
If you have installed the MS-Office Add-In for SpiraTest, SpiraPlan or SpiraTeam and the necessary prerequisites (VSTO and the Primary Interop Assemblies if using the MS-Office 2003 Add-In) but it won't display the Add-In in your instance of MS-Excel, MS-Word or MS-Project, follow these instructions to help us troubleshoot.
