32-bit 4.1 SDK DLLs with 64 bit DSN

Trying to retrieve a UNX universe using the 4.1 Semantic Layer SDK.

Apparently, we need to use the 32 bit DLLs if the universe is uses a

32-bit ODBC DSN. It fails if we are using 64 bit DLLs.

Question is:

    If a UNX universe is using a 64 bit db and DSN, does it require that we

    use the 64 bit SL SDK DLLs to retrieve metadata? Or can this be done

    using the 32 bit DLLs.
