VISA with EXCEL from 32 bit to 64 bitt

Hello,

I am using Excel @64bit, VBA and VISA to communicate with a few istruments by GPIB.

However it seems that I cannot write/read to/from the equipment since when I updated excel from 32bit to 64bit version.
I need a eqivalent "visa32.bas" for 64 bit implementation, I really appreciate any advice or sharing some example.

thanks a lot
Fabio
