COM Add-In "Not Loaded. Runtime error..."

Sep 4, 2013 at 9:08 AM
Hi

I want to test my office add-in on my test machine. I registered it with regasm.exe name.dll /codebase

The plug-in is available in office, but I can't activate it. It tells: "Not loaded. A runtime error occurred during the loading of the COM Add-In"

I checked following:
  • LoadBehavior = 3
  • .Net 4 Client Profil and .Net 4.5 is installed
  • after "OnConnection" in my add-in I added an MessageBox but this do not appear. So plugin do not throw an exception.
Do I Need any more pre-requisites. Or can I get an log file what is going wrong while loading. Or other possible solutions?
