NI-DNET and Windows 7

[pallen]

I am curious if anyone has used NI-DNET drivers with an NI-DNET card using LabVIEW 2010 and Windows 7.

Last year I was performing an upgrade on a customer's system, and after the migration to Windows 7 and LV 2009 SP1 our program began to incorrectly report I/O states.  At the time the customer was not prepared for the downtime required to pinpoint the problem, so we rolled back to LV 8.6, Windows XP, and an older version of the NI-DNET driver. 

We now have another opportunity to attempt an upgrade, but I would like to know if anyone has actually used the NI-DNET drivers with Windows 7 successfully.

Never used NI-DNET, but I assume you've seen this page: http://zone.ni.com/devzone/cda/tut/p/id/10383, which indicates that you need v1.6.4 of NI-DNET for use on Windows 7. Was that the version you had installed?
