Please make comments, problems, etc.
I think it has several problems and is not 64-bit 100%
You are right
the Cognos BI 64 bit version has 2 bibus.exe versions
the classic 32 bit version which uses the 32 bit database clients and the cognos 10 64 bit version which uses the 64 bit database clients and can allocate much more memory
which problems do you encounter?
