Errors during online software registration

Issue

When you tried to register and activate your AutoCAD-based software online, a registration error was displayed in the Register Today screen.

Examples:

The serial number you entered is not valid.  Try again. (1)

Registration-Activation Error (10)
You have exceeded the number of activations allowed for this product.

Solution

These registration errors typically indicate a problem with either your serial number or the connection to the Autodesk registration servers. Please contact the Registration and Activation Codes team at 800-551-1490 to obtain an activation code. This team can also help diagnose issues with your serial number which may be preventing successful online activation.

Note: If you are using machine imaging software, such as Symantec Ghost, to distribute your Autodesk software and you receive a Registration Error 10 when you try to start the software, please see the following solution for additional details: Registration error after using imaging software to distribute MSSA licensed product.
