Activating your copy of Papers
After you have bought a license for Papers you will have to activate your copy on your Mac or PC. You can activate your copy of Papers on a maximum of three Macs or PCs at the same time.
This is how you activate your copy of Papers
- On Papers for Mac choose Enter serial number to Activate... from the Purchase menu.

- On Papers for Windows choose Activate Papers... from the Help menu.
- This will bring up a sheet where you enter your Papers2 serial number:

If you did not receive your P2 serial number after purchase please contact us and send us a copy of your Paypal receipt
- Enter your Papers2 serial number in the textfield. Your Papers2 serial number should be in the format P2-XXXX-XXXX-XXXX-XXXX.
If you only have a Papers1 serial number (which start with PAPERS) you will first have to upgrade it by following these instructions:
- After you enter your serial number click Activate to activate your copy of Papers.
Activation requires an internet connection, see below if you don't have one
Moving to a new computer.
Normally the best way to move your library to a new computer is to copy the entire Papers folder (the one with the Library.papers2 file and the PDFs) to your new computer and then point Papers to this copied folder by going to the library tab in the Papers preferences/options.
Papers should automatically propose to activate this copy of Papers:

- Click Activate to activate your copy of Papers.
What to do when you lost your serial number
The dialog where you enter your serial number contains a Lost License.. button in the lower right corner. Click it and enter the email address with which you registered. We will send you the serial number by email.

Manually activating your copy of Papers2 on your computer.
Activating your copy of Papers requires an active internet connection. If you don't have one, or your institute blocks our website, follow the instructions that are presented to you on a Mac by clicking the activate while holding the alt/option key, or on Windows by going to Help-menu Manually Activate Papers. This will bring up a dialog explaining how to manually activate your copy of Papers.
You will need to save an activation request file that you can upload here from a computer with an internet connection. This then allows you to do download an activation code file and you need to bring back to your computer. On Papers for Mac drag the activation file onto the Papers icon and on Papers for Windows use the Import-button on the manual activation window to import the activation file. This should now activate the program.
How do I deactivate Papers on your old computer?
In contrast to Papers1 you no longer have to deactivate your old copy of Papers before you move to a new computer. If you have reached your limit on your old computer you will be presented with a list of machines on which you have Papers activated. You can decide to either deactivate Papers on one of your old machines or to buy an additional license.
