COM Dll Register Error

Member 8132177 asked:

Open original thread
Hi Team,

I have converted COM dlls in VS6.0 to VS2010. while debugging the COM dll code by giving C# GUI as the executable. Getting the following Exception.

"Retrieving the COM class factory for component with CLSID {uuid...} failed due to the following error: 80040154 Class not registered (Exception from HRESULT 0x80040154 REGDB_E_CLASSNOTREG));"

This was coming when calling constructor of the class in SLCOREINTERFACELib
objCoreinterface = new SerCoreInterfce();
where objCoreinterface is null and jumping to the above exception

When i try to register the COM dll using regsvr32 is giving Dll register successful. But i could not able to see the entries in REGEDIT.

How do i solve this issue. Is there any possibility that i can delete all the references to the COM dll in Registry and re-register again.Will that solve the issue?

Your quick help will be appreciated.

Thanks.
