Need procedure for loading earlier version of NI-DAQ

[ben c]

I'm using a legacy DAqCard 1200 in a Dell Inspiron 7500. PII- 400 with 320 MB ram. Labview 6.1 crashes due to invalid page fault when some Daq VIs are called. NI.com shows I need to use NI-Daq 6.9.1 or earlier. I downloaded the files and searched the knowledge base. There are postings about installing earlier versions of NI-Daq, none concerning LV 6.1 with 6.9.1. I keep getting errors due to wrong files during install. Does anyone have the correct procedure to perform this setup?

If you have not un-installed the newer version of NI-DAQ, you should do that first, then try installing the 6.9.1 version.

If you continue to get errors, there's a utility available from NI that will clean up all references anywhere to NI software so you can do a clean install. During the reinstall of LabVIEW, be sure to do a custom install and tell it not to install any drivers. Then install the 6.9.1.
