# Transferring an activation
To transfer an activation for all registered modules, press the `Deactivate` button on the `About EasyCatalog` dialog.
Highlight one serial number and click Deactivate
To transfer an activation for an individual module, highlight the serial number that you would like to transfer in the list of active modules and press the `Deactivate` button.
After a few seconds your serial number will deactivate and you should be able to activate the serial number on another machine in around 5 - 10 minutes.
If you have any problems with activation, please contact us using the [contact form](https://nousmedis.com/en/get-in-touch-with-us/) on our website.
