LabVIEW 8.0 not opening any longer

[nuty17]

LabVIEW will just spin it's wheels upon attempting to open with no splash screen nor interface.  It does not eat any processor clock; just sits there.    The application icon does appear in the taskbar.  If I right click on the taskbar icon, the only option I have is to close LabVIEW.  This causes the "Unresponsive Applicaiton" window to open and I have to force-quit LabVIEW.  If I try to open a VI, after a few minutes, the exact same thing happens except after a few minutes a dialog box pops open informing me that LabVIEW can not find the path to the VI I have tried to open.  It then directs me to Windows' search window to look for the file.  LabVIEW has been installed for about 2 weeks and running fine right up until now.  The afternoon before I started hving these problems, I did click the "Save All" button inside of the Project I was working on...and it did the wirdest thing...It tried to save all of the VI's in the project with strange ascii characters instead of their correct names...

Sensing application corruption, I've tried the following:
I have tried repairing...to no avail.  I have tried uninstalling then reinstalling...also to no Avail. 


Does anyone have any ideas?

I would suggest uninstalling LV again and then using msiblast.exe which can be found on ni.com. then after running the blast utility I would try re-installing labview and see if this helps.

Thanks for the reply!!

I just got off of the phone with NI's support and they suggested deleting the LabVIEW.ini file found in the app. root directory.  Amazingly, that did it!!  Even more amazing however is the fact that the repair utility and a COMPLETE uninstall/reinstall operation somehow managed to miss the corrupt LabVIEW.ini file...strange huh?

I'll try that msiblast.exe if deleting the INI file fails to fix any future problems

That would have been the first thing that I said but since you had already done a complete uninstall/ re-install I figured it would have put a fresh ini file in for LV when you tried to open it after the installation.

Good to hear you got it going again though.

Just FYI,

Even if you uninstall LabVIEW, the .ini file is still going to be maintained on your harddrive. So if you reinstall LV then the old .ini file would be loaded.

The reason for this is because, the .ini file contains a lot of LV environment settings and one would like to have the same working environment when LV is reinstalled.

So even if you would have reinstalled LV, you would have noticed the same behavior as before.

As an extension to Chetan's reply, another reason uninstalling does not remove the INI file is that the uninstaller only removes files that the corresponding installer installed.  The INI file is not installed by the installer at all - it is created the first time you launch.

Both of these reasons make pretty dern good sense.  There's been many a time when I've been on the other side of the fence wishing an application uninstall did have a way to remember previous install's settings.  I'll pass all of this information on to my colleagues.
