As much as I love doing business with NI, they did it this time.
I loaded run time engine 8.0 on my main computer (I made an executable with Applications Builder on another one). After I installed, I rebouted the computer (as I have been asked) and...
"...missing or corrupted HAL.DLL"
It took me a whole day to revive my computer.
1)I had on that computer a LabView 8.0 Demo expired.
2)I had a copy of run-engine 7.x (I forgot about it)
3) After I revived my computer I tried (in safe mode) to remove LabView and components. It didn't work.
4)I was able to remove all of them just as I am writing this, and after removal, the NI uninstaller asks me to reboot the computer. My 24 hour work for nothing started with the same message from the NI installer...I don'tknow if I dare. As I remember , NI uninstaller is the only one asking to reboot after removing a program. Is there, around, a Wizard of Programming able to tell me if this is OK?
