PowerPoint Add-in working on Windows 7 Enterprise edition but not on Windows 7 Pro

Question

I have created a PowerPoint add-in using C# VSTO and using msi installer for the deployment.

The Problem is that on every system at my end(all Windows 7 Enterprise edition), the plug-in is working fine, but on users' machines(Windows 7 Pro) either the ribbon is not visible or the events are not working.

My concern is, am I missing something which I need to take care of during the development? Thanks

This is one of the reasons that VSTO deployment is a pain. You have to understand every dependency of your application and the dependencies of your dependencies and then make sure you cover all of them for every version, flavor and bitness of windows and office that you can think of. Then you come to find out that a user has a Click To Run version of Office installed that generally doesn't support AddIns anyways.

There are so many possible failure points in the chain that no one could possibly tell you the cause of your problem. A lucky guess perhaps but that would be it. To date I've created VSTO installers for 6 companies and even with my background knowledge and prebuilt templates they are still labor intensive projects because of the test surface that is involved.
