Labview 8 will not launch

[Christian_nor]

I don't know what has happened  

Labview worked perfectly on friday, but this morning it would not start at all. First I tried the install repair, then I uninstalled LV and reinstalled it, then I uninstalled all my NI software and reinstalled it and still LV refuse to start

When I launch LV, I get the window indicator (don't know the name) next to the windows start button, but nothing happens. Then my system says LV "not responding"!

What is wrong??!

By removing the old Labview.ini file I was surprisingly able to launch the program. Can anyone tell me why? And why wasn't that file removed when I uneccesarily uninstalled and reinstalled LV?

Uninstall will only remove the files that were installed. The ini file was created by LabVIEW on first launch (since one did not already exist). This logic is usually a good thing; you don't usually want to lose your customized settings.

If you will attach the ini file that was causing the hang, we will investigate the problem.

Thanks,

Hi,

here is the stupid .ini file....

I would appreciate if you could tell me why this happened.

The line in the file causing the problem is:

FPFont="" 120 I

LabVIEW will create this token via Tools >> Options >> Fonts, click Font Style, then check Front Panel, OK out of the dialogs, then exit LabVIEW. The quotes are for the font name ("0"-"2" for app, sys, and dialog). The number following that is the point size (120 is really really big). The trailing "I" means italic. The part of this token causing the problem is the blank font name. I played around a bit and can't get LabVIEW to write blank for this. Do you happen to recall what you might have done to get here?

Regardless though, I'll file a bug report to have our handling of the ini setting improved to handle this case.
