Hey Ricardo,
We built and tested Smoke using 32bit. You can try and build and run 64... let me know how it goes!

thanks for the answer
it sort out my problem

FWIW, it is a 32-bit binary and it runs fine on the 64-bit versions of Windows Vista and Windows 7.

The actual Generation of procesors support both modes , even if you run a 32 bit programs on a 64 bit OS (at least in Windows) it should run normal also , it will include the limitations of a 32bit OS

Thank you for
let me participate
