Troubleshooting COM Add-In load failures RRS feed

  • Question


    How I can troubleshooting COM Add-In load failures?

    We have problem with addin in Word, Excel, and PowerPoint on users’ laptops. Addin is installed but it is in state unload. We deployed VSTO office 2007 add-in to all users of machine (after installing Hotfix kb976477). It is deployed on 64 bit Win7 OS. Office is 32 bit. Prerequisites are VSTO 3.1 and 2007 Microsoft Office Primary Interop Assemblies. Add-in works with our Sharepoint 2007 document libraries. Enabling from the office or in the registry (in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\Word\Addins\UHC.SharePoint.DMS.WordAddIn loadbehavior = 3) does not work. I cleaned up registry, reinstalled office, reinstalled addin, and still installation is successful but addin is unloaded. It is not in disable addin list.

    I  am following steps of article, but I did not find solution.
