I had purchased the teacher/student version. The product code appears to be, at least supposed to be, on this trifold insert where MS has put a reminder telling me not to lose it. I assume it is supposed to have had a sticker on this trifold. It does not appear there was ever a sticker there, that is, no glue residue or any thing is there.
I also realized I have this in the wrong forum. Hopefully a Mod can set it right. Thank you
