Hi, We have reinstalled one PC today, when we try to activate the licence of 3DS Max we have a message
The serial number you entered is not valid. Try again. (1). What can we make?
Welcome to the Forums!
The most common issues with receiving an invalid Serial Number error are:
- Inputting the incorrect Serial Number into the incorrect year of product. Each release has a separate Serial Number - check you are inputting the 2012 Serial Number into the 2012 product.
- Upgraded licenses. If you were previously on Subscription and then let it lapse, you are no longer entitled to use Previous Versions of software. Make sure you are using the license you were most recently upgraded to.
If you have checked the above points and are still having difficulties, please sent me a Private Message (click on my amanda.k profile name and then “Send this user a private message”) with your Serial Number and Product Key and I will further research this for you.
Hello. Thank you very much for quick reply.
Yes, I think is the second case that for us.
Recently we have bought updating to version 2013 but we still have the problems with activation.
