This topic provides troubleshooting steps for resolving activation issues.

You have exceeded the maximum number of application copies that can be installed with one license

The error message is displayed when a serial number is activated on more computers than the license allows.

When you purchase a product from Devart, you get a serial number. It enables you to activate the software multiple times depending on the number of licenses purchased and the terms of the license agreement.

If the limit is reached, the error message appears.

To fix the problem

Deactivate the product on another computer to free up a license.
Purchase more licenses.
Contact Devart Support.

Your license doesn’t allow you to use this product

The error message is displayed when either the serial number you entered refers to a different edition of the product, or your license has expired.

To fix the problem

If the serial number is for an older edition of the product, and you don’t have that version installed on your computer, download the correct version from the Devart website.
If you face issues upgrading your product, contact Devart Support.
In case your license has expired, purchase another one.
If you think we have disabled your license by mistake, contact Devart Support.

Your license number is incorrect

This message is displayed when either the serial number you entered is not registered with the activation server, or there is a problem with the format of the activation request.
