Hello!
We found out that this bevavior just happens if you have a Virus on this specific Computer.
In this case it might be the W32.MAGISTR3392@MM Virus.
There are tools to remove this Virus, but it might happen that your Data is Corrupt.
When something like this happens, try to compare the EXE File Size with yours.
