Thank you Allan,
When I previous attempted this I was mistaken to believe that the computer used to make the ISO had to be WinXP. Of course I have Vista.
I will attempt this again with your encouragement.
Another question: I also have Win2000Pro; Win2003Server; and NT4. Are any or all or none of these candidates for N'lite treatment.
Hate to be a stickler on these old softwares, but my main programs are AutoCAD2000 and AutoCAD2000LT. I tried using the wizard to emmulate early Win OS in Vista with very poor performance.
I'll keep you posted, but it might be the weekend before I try....
Thanks,
John
