We traced our problem to a certen level, we installed all the programs that we normal use, program ( vi ) keeps working.
If we use a image of windows and pré installed programs, than we get the "error".
The problem or "disfunction" lies in that image, so every pc that is installed with that image has the same problem.
To solve the problem we have to look what the difference is between that image and the original installed pc, but that shoud take hours, days, weeks.... ??
So if we want to use the vi we just have to reinstall our pc without using that image.
I think i can say case closed
