I'm migrating an application written using VB6 and ArcObjects to .NET
After a machine rebuild, the application started to fail with the above error when OnCommand_OnClick is executed.
The project properties Complie tag has the target machine set as X86.
I have tried to register associated DLLs using Regsvr32 but this results in "****.dll was loaded, but the DllRegisterServer entry point was not found. This file can not be registered" I have also ran (again) the regasm utility on the main DLL but still get the above message.
