Having upgraded to Windows 7 and reinstalled Inventor Suite 2010, I can't get a new activation code. I've double checked the serial number and it is correct. This was the version I had Instailled on Windows XP.
EDITED TO REMOVE LICENSE INFO
Hello Osunlade and welcome to the community!
I moved your initial posting to our Installation and Licensing board and edited it to remove your licensing info as this is a public forum.
It looks as though your AutoCAD Inventor Suite 2010 serial number has been upgraded to Autodesk Product Design Suite Premium per a Subscription Contract, of which all 3 seats have been activated. Please contact Gordon Mcintosh if you have any additional information on the usage and or let me know if you need additional clarification.
