NI-DAQmx simulated instruments in LabVIEW 2009 causes MAX under Vista to crash

[jesses]

On a Vista Ultimate machine that successfully ran LV 8.6.1 and MAX I am having a lot trouble creating a simulated instrument using NI-DAQmx under MAX 4.6 with LV 2009.  When I try to create the simulated instrument, the program will just sit there until I get the message 'Program Not Responding' in the windows banner area.  At that point MAX crashes.  Moving the LV2009 installation to an XP machine I am able to create simulated instruments with no problems.  Is there a solution to this?  Right now I about ready to uninstall LV2009 and MAX 4.6 and reinstall LV8.6.1.

I have not heard this reported as an issue with the drivers or MAX on Windows Vista.  Are you using 32 bit or 64 bit Vista?  Also, which version of the DAQmx drivers do you have installed?  Does the program hang regardless of what device you try to simulate, or only with specific ones.  If yoú haven't already, I would recommend repairing your installation of MAX and DAQmx, and upgrading to the latest DAQmx drivers (9.0), if you do not already have them. 

Let me know if this solves your problem.

Looks like we're experiencing a similar problem here today. 

MAX version 4.6.0.49152 has suddenly become unstable after creating a simulated device.  

A newer version of the DAQmx drivers had recently been installed over an older version.  Current DAQmx is 8.8.0f2  This is on a Sony Viao laptop running Vista 32 bit.  

I don't have all of the details at the moment.  But it appears that MAX and DAQ functions had been operating properly after the upgrade up until the point of trying to create a simulated device.  After that, MAX could no longer access the simulated devices and would simply stop responding when attempting. 

User is going to attempt a repair.  If that doesn't work, we'll try MSI Blast.

Hello Patrick,

If you are using LabVIEW 8.2 or higher I would recommend upgrading to the latest version of NI-DAQmx (DAQmx 9.0.2).  If this was a reported bug the new driver would have the latest fix for it.  Try this out and let me know if it works for you.

Jesses,

If you upgraded to LV 2009, you will have to upgrade DAQmx to at least version 8.9.5 or higher. 8.9.5 is the earliest DAQmx version with support for LV 2009. Because both DAQmx 8.9.5 and LV 2009 ship MAX 4.6 and previous versions of  DAQmx shipped earlier versions of MAX, you may be running into a DAQmx/MAX compatibility issue.

Let me know if upgrading helps your situation.

Pallen and Jesses,

Would you mind telling us the upgrade history so we can try to reproduce the issue here?

Also, if MAX is still usable, you can also generate a technical report (File»Create Report...) and post it here.
