I'm trying to transfer a license (autoCAD LT 2012) from one pc to another.
However when trying to transfer the licence with LTU I get the error message "The serial number you entered is not valid Try again. (1)".
As suggested in another thread, I uninstalled autoCAD on the first pc, and installed it on the other one. During the installation my serial number was accepted. Installation completed succesfully but during the activation I got the same error message again.
How should I proceed?
The LTU will only work with assets that haven't been upgraded unless that upgraded asset is attached to a valid Subscription.
In your case, it appears that all of your AutoCAD LT 2012 license were upgraded to 2013 per a Subscription that has since lapsed / expired, which would also explain the activation error.
You would still be entitled to use the 2012 license if the If the 2013 ones have not yet been activated. Alternatively, you could also utilize the 2013 license which in doing so would forfeit all future right s to the previous / 2012.
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 (I show several AutoCAD LT 2012s on your account) and let me know if you wish to stay with 2012 or upgrade to 2013.
Please also note that for future needs, you can also contact our Registration and Activation group for direct assistance.
