It appears that there is an issue with your account where the only workaround would be to create a new Education Community profile with a different email address. My apologies for the inconvenience and please feel free to let us know if you have any additional questions or concerns.
I have same problem, when I tried to use the serial number to register it says "The serial number you entered is not valid. Try again.".
There is also an issue with your account preventing the license info form functioning properly, of which the suggested workaround is to create a new Education Community profile with a different email address.
I am having the exact same problem. "The serial number you entered is not valid. Try again. (1)" Please help as we are trying to install on our new computers.
Did you receive this license from the Education Community? If so the workaround would be to create a new account and obtain a new license, however I wanted to note that the free licenses are for personal use and should not be installed on lab machines.
If you didn't receive this license from the Education Community, can you please send me a Private Message (click on my philip.s profile name and then "Send this user a private message") with your serial number so that I can troubleshoot accordingly.
I've got some problem with the software activation, or I'm not sure that is activated now or not.
So, I have downloaded & installed both the AutoCAD 2013 and Inventor Professional 2013 student-version. After installing, I started the softwares, and I wanted to follow the following activation proccess: http://usa.autodesk.com/adsk/servlet/ps/dl/item?si
But after Step 1, when I accepted the agreement, a little window came up which said 'Licence veryfing...', or something like this. Then once this window said 'Licence verified', and the softwares have been loaded.
Does it mean it is activated, or how shall I activate these products? I tried to register them at the http://registeronce.autodesk.com site, but when I enter the serial number (which I can see on the software download's site), it says, 'The serial code you entered is invalid. Try again. (Code 2)'.
Thank you for your help in advance!
What happens when you open the software? Does it go through the checking license screen again? What happens after that?
