You receive the following message:

You've exceeded the maximum number of activations for this serial number


Too many activations


You exceed the limit of available activations. For example, you have an Acronis True Image 2021 1 computer license and attempt to install Acronis True Image on more than 1 machine.

Other possible causes:

  • You reinstalled or upgraded your operating system.
  • You upgraded your machine with new hardware.
  • You replaced your machine with a new one.

If you want to use Acronis True Image on more machines than you license allows, you will need to purchase additional serial numbers and activate the new copies.

If you have reinstalled or upgraded your operating system or hardware, or simply moved the product to a different machine, reactivate Acronis True Image in the new environment.
