VISA with EXCEL from 32 bit to 64 bitt

[fabio76]

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

You need to be more specific about what does not work. While I haven't tried it myself I did take a quick look in the visa32.bas file distributed with one of the latest VISA releases and it should actually simply continue to work. The visa DLL name changed to visa64.dll but NI-VISA installs alongside a visa32.dll that simply forwards all calls to the real DLL, so there really should be no problem there.

Have you installed NI-VISA on that computer? https://www.ni.com/nl-nl/support/downloads/drivers/download.ni-visa.html

Can you be more specific as to what does not work?
