Yes I did; please read the first post (regarding the problem) in this thread. It has most of the details you would want.
Ah, sorry, I read it but somehow skipped that sentence...
I am running out of ideas, but these are the things I would try:
- run a registry/installation cleanup utility (I can't recommend one, but Google will help you)
- install some driver/tool from NI that doesn't require LabVIEW (for example NI System Configuration) and then try with LabVIEW again
- use Windows backup to restore your computer to the state from before the reboot (provided that you had Windows Restore enabled)
If it is Windows 7+, perhaps check C:\ProgramData\National Instruments. (ProgramData is a hidden directory, so you will need to set folders to view it. I'd not delete it, but perhaps change its name.)
