I built AddIn.dll (MFC, Interface _IDTExtensibility2) for Outlook.
It has always been executed by Outlook, even it wasn't 'registered' through ... - Options - COM-Add-Ins
When I renamed AddIn.dll to AddIn1.dll, Outlook didn't execute it any more.
After renaming back to AddIn.dll Outlook still refuses to execute my AddIn.dll
I tried 'registering' my AddIn.dll through ... - Options - COM-Add-Ins, but AddIn.dll is not showed there
What can I do, that Outlook executes my dll again ?????????
