From: tadk on 10 May 2006 21:40 I have been using Labview 8.0.1 and Teststand 3.5 on my laptop for a few weeks (eval versions) during the time I don't have access to my PXI platform. Today when I tried to shutdown my laptop, Labview would not shut down and could not be terminated. After 10min or so it finally shut down. After reboot of the system, labview hangs on startup during "finishing intialization", and must be terminated. I cannot launch it at all. Please tell me there is a way to fix it without reinstall.

Before I installed all this NI stuff, it would take seconds to shutdown. I can see there are 5 or 6 NI agents running right from boot. Even if you aren't planning to use labview, they have already consumed a good sized chunk of memory.
From: tadk on 12 May 2006 00:10 OK, deleting the ini file did not solve the problem. I tried a repair on the labview component and it seemed to complete, and then it tried a repair on Ni-DAQ 8.0.1 even though I had not requested that. This hangs up at "shutting down services". Since its not repairable, I tried removing all components with DAQ in the name. This also hangs while trying to remove NI-DAQmx 8.0, and even though it does not give details, I suspect it is trying to shut down those same services. You cannot cancel out of the remove procedure unless you terminate just about every running process. Later I found that nipalsm (2 instances) and nimxs are processes which cannot be terminated in task manager. Somehow they do get terminated in a normal shutdown, but I have not seen one of those in a while. Next step: installing over the exising Ni-DAQ.

We might be able to help you in cleaning your system. Regards, Ankita Agarwal Applications Engineer National InstrumentsMessage Edited by Ankita on 05-12-2006 05:05 PM

Tech support suggested a few options the first being delete the ini file, reboot, launch labview and give it up to an hour to sort things out.This didn't work. Option 2 is the repair, which didn't work because windows couldn't shut down the running NI agents. Option 3 is uninstall, delete Labview folders, reinstall, which was also failing for the above reason. My solution was to identify those problem NI agents that were running (40MB worth!), rename those exe files so they could not re-launch, reboot and uninstall everything. I think my problem may have been due to the scattered way I did my original install. I had downloaded the various pieces at different times but I think there were some 8.0.1 mixed with 8.0 and probably not installed in any particular order. I have now reinstalled from the non-eval 8.0 CDs and I plan to avoid 8.0.1 if possible. Hopefully this will prevent the problem recurring since the fix takes 1-2hrs. It is promising that my shutdown time is only 30secs or so instead of minutes. These are the obvious NI agents which run from boot. There may be others with less obvious names: nidevmon.exe, nipasm.exe(1), nipalsm.exe(2), nisvcloc.exe, nidmsrv.exe, nimxs.exe I can understand one such program may be needed to launch others as needed, but six!? Programs which launch and run without your request, using resources and providing no benefit are often called parasite programs. |
