    I'm trying to update my plesk panel from 8.3 to plesk 9.0 and i recieve this error: windows cannot open this program because the license enforcement system has been tampered with or become corrupted.

    I downloaded the file from parallels website.
    If i try to update the plesk from 8.3 to 8.6 i recieve the same error.
    Does anyone knnows why?
    Thank you.
