nidaq32.bas and Windows 7

Hello,

I have successfully installed NI-DAQmx on a Windows 7 64-bit machine. I can control a PCI-6503 from the test panel in NI-max. So far so good...

I have a VB program that I was using on a Windows 2000 machine, using a PDIO-24 card, that made calls to nidaq32.bas. 

When I try to run the VB program on the Windows 7 machine, using the PCI-6503, I get an error.

When I try the Dig_Prt_Config command I get an error:

(10040) Module could not be loaded.

What should I do to troubleshoot this?

Thanks,

Geoff
