Read about the documentation yourself but you need to provide 2
different versions of the tlb for 32 and 64 bit platform.
One possible solution to guard these tlbs with some x64 macros. Like
#ifdef _X64_ // or your x64 define
1 TYPELIB "TellerCaptureX64.tlb"
#else
1 TYPELIB "TellerCaptureX.tlb"
#endif
Ofcourse you will need to build that tlb on a x64 system. Pay attentation not to fetch the x32 binaries.
