I'm an IT administrator and have purchased a few Autocad LT licenses that I have installed on user computers (one for each user).
One of the computers that I installed this on had a pretty serious Windows problem not related to Autocad, so I reformatted and reinstalled it. I installed Autocad again on it, which went fine, but once the user wanted to start up the program, he gets the message as attached:
I'm sure you'll all forgive me for wanting to keep my product serial number to myself, this is the same serial number as the one on the packaging, but the product key is publicly known and this is what I'm having problems with.
I see that other users seem to have the same problem, but it always seems to be solved with private messages. I also tried to contact my supplier, but no luck.
Why will it not accept the Product key?
Can anyone help me?
As crazy as it sounds, I have seen this fail if the product key is copied and pasted into the box, rather than simply typed. Try typing it manually.
Also, if you installed this from the Inventor LT Suite, it could be 529D1.
