labview .net runtime error on startup

Hi.

I was trying to clean my XP (SP3) system up and uninstalled and reinstalled Labview FDS. Now Labview only momentarily starts up and then crashes.

The even viewer reports ".NET Runtime 2.0 Error".

other info:

Faulting application labview.exe, version 7.0.0.4000, stamp 3eb1302f, faulting module unknown, version 0.0.0.0, stamp 00000000, debug? 0, fault address 0x05c4bad2.

Any ideas how to get this working again?

I've reinstalled / repaired .NET 4 and tried reinstalling and repairing Labview but no joy.

I have a string of users who need this running again so any help much appreciated.

Rich.
