64 bit dll register

I have converted 32 bit COM dll into 64 bit dll by using x64 build.I tried to register this 64 bit dll into 64 bit windows 2008 server uisng C:windows\system32 regsrv32.exe .But i'm getting an error message "Dllregister server failed with error code 0x80029c4a". How can i register this dll in 64 bit OS.

That error code is TYPE_E_CANTLOADLIBRARY which likely means there was a call to LoadTypeLib() somewhere inside DllRegisterServer() and that call failed for whatever reason. A likely reason is the library was not added into the DLL resources.
