Removing Activations from a License
If you reach the maximum permitted number of activations for your license key, and would like to remove a machine from the license in order to free up a space for a new machine, you can follow the steps below to do so:
1. Log in to your PDF-XChange account here.
2. Go to the Your Products and Serial Keys tab, and then click Activations List:
The Activations List will open:
All machines that are currently registered on your license are detailed in the list.
3. Click Deregister to deregister a machine from the Activations List, then click OK in the confirmation box to confirm the deregistration. A free space will then be available on your license to add a new machine.
Note that the license keys for PDF-XChange software are assigned a specific number of users, and each user is permitted to activate the license on two machines - a desktop PC and a laptop/touch-based device - provided that they are the primary user of both machines. For example, a five-user license key is permitted to be activated on ten total machines. When the activations limit is reached it is no longer possible to use the license key to activate the software on additional devices. If you want to do so then it is necessary to first remove a machine from your license, as detailed above.
