Problem launching Labview 8.0.1 on WIN XP Pro PC


Recently updated LV8.0 to 8.0.1.  Everything appeared normal and I worked a couple days on front panels.  Suddenly, after a normal bootup, when I launch LV, "LabVIEW" shows up in Taskbar, but NI screens ever show.  Windows says program not responding.
If launch again, a second "LabVIEW" shows up in Taskbar, which also does not run.
  When attempt to close task from taskbar icon, get the "Program not responding" message box.
Any ideas on what is wrong?
Other apps run fine on PC.

SGCO,

Have you tried rebooting the machine? How about reinstalling the patch or if necessary the base application then the patch? Was any other software installed since the patch?

cheers,

Turns out this is a known bug in LV8.0.  The LabVIEW.ini file sometimes gets corrupted, and this behavior results.  NI tech support says the reason is not known yet.  The fix is to delete the .ini file and let LV rebuild it on launch.

I am actually struggling with this again as we speak. This seems to happen to me about once a month. The first time I fixed it by doing a repair installation (that failed on a stuck process, manually disabling the stuck service, and repairing again). The next time it happened, I started by deleting the LV8 .ini file, and that seemed to work for a few months (I had to do it more than once). Now, I'm back where I was to start. I tried the .ini trick, no dice. Tried a repair, froze on the stuck service. Restart, kill the service. Repair again. Hopefully it will work after this.

If anybody cares, this time the stuck service was the tag server (I'm not sure if it was the same the first time). Also, like you described, the task manager doesn't ever seem to be able to kill LabVIEW when this happens. I always have to restart to get rid of it. A log off doesn't get rid of it either. I think this has something to do with the problem being a service.

I was starting to think there was just something messed up about my install (I have a concurrent 7.1 install), but I keep seeing messages like yours pop up. I guess I should try removing all LV stuff and installing from scratch some day. I don't really need the 7.1 install anymore, and it's a bear to get the toolboxes installed with it there anyway. Unfortunately, it always seems to happen when I have a report immenently due. D'oh!

In any case, I would try deleting the .ini file first, and see if you can start without it. It will automatically recreate it, and then you'll have to go back and reset your prefs manually. At one point I tried saving a backup .ini file when LV was working, and I think I was able to replace the "corrupt" version with that once or twice, but even that failed at one point (deleting it entirely fixed it on that occasion).

C out.

grrr! Looks like it got stuck "Stopping" nipalsm.exe this time. I'm just going to kill everything and start from scratch. It wouldn't be so bad if I didn't have to restart every time. NI, if you could somehow make it so I could program LabVIEW for Windows from a Mac, I would be eternally grateful!
