i aded for the MIDL Compiler options /env x64 /x64 for X64
when i checked for the uuid 96c64c60-24f6-99d0-9f8c-0020af9099cc in the widows registry it was not found at all.

when i checked the Files which the MIDL Complier Generate i could see that it was possibly not may was not correct switch to X64

/* Compiler settings for D:\Home\Atiras\V77Ma_64Bit_Branch001\Src\Cm\NmsCmCommon\ITopolog.idl:
    Oicf, W1, Zp8, env=Win64 (32b run), target_arch=AMD64 8.00.0603 
    protocol : dce , ms_ext, c_ext, robust
    error checks: none

         __declspec(uuid()), __declspec(selectany), __declspec(novtable)
         DECLSPEC_UUID(), MIDL_INTERFACE()
*/

can it be that with this MIDL compiler settings the are not created any registry an the class is not registered an what are the correct switches then ?
