Hi, when trying to install some Adobe CS5 product as a trial receive, I this error: 
 The setup program has encountered an error during installation (and 20). Restart the computer and run the process again. 
 Restart does not work. I have a Core I7 with 6 GB of RAM, Windows 7 bit 64th 
 The same on my notebook works without problems (; synonymous with Windows 7 64 bit)
