I have in it that format. I entered in my cd key using nlite, so when I look at my winnt.sif, it has quotations around it. I didn't know if this was a problem, so I took out the quotes and it's in that format, but when I test it in Virtual PC, it still stops and asks me to enter in my cd key. Is that something with Virtual PC, or is there something else I'm overlooking? Thanks for the help.
