Hello!
We have the following problem:
LabView (8.2) hangs when using I/O operations with traditional NI-DAQ 7.4.4 after aborting LabView program
We freshly installed LabView 8.2 (2006) and NI-DAQ 7.4.4 on a PC running Windows XP (Service Pack 3). We built a larger vi that remotely controls a traditional NI-DAQ card (AT-AO-10) on a second PC via NI-VISA 5.0.3. We were successfully running this program until a power failure caused the first computer to crash. After this crash we were unable to start the program again: LabView freezes while loading the vi. LabView itself can be started but freezes when adding I/O operations from the NI-DAQ palette to a block diagram.
We have tried to re-install NI-DAQ 7.4.4, but it did not help. We then re-installed all NI software, but still no improvement. In the end we decided to reinstall ALL software, first Windows XP, then LabView and finally NI-DAQ 7.4.4. This worked. However, after a few days of running the program we had to abort LabView via Windows Task manager and afterward we again experienced the same problem as before: LabView freezes when loading the program.
Obviously, we cannot afford to reinstall Windows every time. Are there any known Windows XP / NI-DAQ issues that might cause the freezing of LabView? We would be very grateful for any idea.
Best regards,
Matthias
