why does labview 2009 32-bit closes up with no error message?

[Oswaldo]

Hello.

I am developing an application using a PCI-6534 board, Windows XP SP3, and LabVIEW 2009 32-bits. In this application I am generating a 300 Hz signal using the P2.0 digital line. I am trying to make digital acquisition using the P0 port (8 bits), using N-sampling. The program that generates the 300 Hz clock, works with no problem. However, when I start running the program that performs the data acquisition, LabVIEW suddenly closes up with no error message. The LabVIEW windows just disappear from the screen.

As for me it looks like a LabVIEW bug.

In case anyone decided to help me, I could attach the programs so that you could check them.

What can I do to solve this problem?

Thank you.

The best way to take care of bug reports is to call in to support. You can do this from the support tab.

Can you get any screenshots? Which other program is running?

Also it is a good idea to upgrade to 2009 SP1 or 2010 if possible in case this bug was taken care of in either of those revisions.

I had the same problem with one of our applications. I supplied gigabytes of process monitor and desktop execution toolkit logs, but nothing was resolved. I upgraded from WS2003 and LV2009sp1 to W7 64b and LV2010, per NI's recommendation but the problem persists.  I had the corresponding service ticket open for 3 months where NI said the application ran fine for them on W7 with 2010. (long story) 

I understand your frustration, and I recommend getting your local application engineer involved as an advocate with application support.. If you pay for service, pound on them to provide it. My $0.02.
