pb viopen win16 exe under windows 2000

A win16 application generated with Labwindows CVI 3.1 doesn't work under windows 2000.
I get a 0xBFFF0000 error with viopen.

The board is a PCI-GPIB one. With MAX I can see and dialog with the Hp34401a multimeter.

I tried to run with ni488.2 version 1.7 and 2.2 without success.

I did compile again the application - no more success.

What can I do then ?

Note : in the project I don't see how the visa.dll has been linked. With the ni488.2 there is no header file for visas dll so I did use the visa.h that was already in the project.

Thank you very much for your help.

Finally it was very simple. I just had to install an old version of ni-visa for windows 16 bits.
