Dear Andrew, first of all, thank you for your reply. I agree with you: it is an installer problem. The point is HOW to "bypass" this problem. The only feedback I get from the OS are: 1. "Cannot find C:\windows\system32\ANG45.LAN" 2. " (yellow triangle followed by) upset.exe". Basing on these, is there anybody that can suggest me HOW to set up the "bypass"? I made the question to Auralog, that simply answered: "Sorry, the SW is not anymore supported". Microsoft should grant the backward compatibility, I guess. But this is not the case. Once again: is there anybody who can help me?
