I want to share an issue I faced a few weeks ago that took me around 1 week to get solved.
This issue is related to a .NET User control exposed via COM interop to be accessible from MS Access 2010.
Despite the Usercontrol is registered in regasm using regams /tlb myUC.dll, every time I placed a instance of this .NET "Activex" control in a MS Access form I got this error: "OLE Server isn't registered"....
