The licence enforcement system has been tampered

[jerry2]

Hi there

I tried upgrading 2 of my Plesk 8.2 servers and I got message when I click on the plesk compressed exe:

Windows cannot open this program because the licence enforcement system has been tampered with or become corrupted.

What is going on?

Seems the network install 650Mb file is corrupted. Normal installed worked.
