The demo version that you can freely download from our web site has the following limitations: it lets you backup/sync max 40 files (from both the source and the destination folder). To unlock these limitations you should purchase a license at our web store. After you have purchased a license we’ll email you with your registration data. A license allows you to simultaneously run FoldersSynchronizer on two machines per time.

Authorise your computer
If you run FoldersSynchronizer 4.3 or higher, the registration data consist in a Serial Number & Email that you have to enter on the Registration Panel.
  1. Be sure your computer is connected to the internet then launch the FoldersSynchronizer application. At the first launch you will be shown the Authorization panel.

  2. Enter your Serial Number and Email then press the Register button. The demo application will turn into a full working application and will run without limitations. From the second launch on you don't longer need to be connected to the internet to launch and run FoldersSynchronizer as registered.

If you run FoldersSynchronizer prior versions than 4.3, we will email you with a RegistrationFile.txt containing an encrypted text with your Serial Number and Email. Do not rename nor open nor modify the RegistrationFile.txt.
  1. Put the RegistrationFile.txt file in a folder together with the application FoldersSynchronizer, as shown here aside. This file turns the demo copy into a full working copy.

  2. Launch FoldersSynchronizer.

  3. Leave this file as is in the FS folder and your copy will be running as a full working copy, forever.

Be sure your machine can run applications from identified developers (see the System Preferences/Security/General panel). If you run on macOS Sierra please consult this article on “How to Disable Gatekeeper and allow apps From identified developers in macOS Sierra”.
If you purchased a multi user license, you can enter your Serial Number & Email to as many machines as your license allows. When authorized, FoldersSynchronizer will tell you how many additional activations you can still make. Remember to deauthorize your machine before you sell it or give it away. See the next chapter here below.

If FoldersSynchronizer doesn't run as registered, please check these solutions.
Deauthorise your computer
If you need to move your license to a different computer, or if you are going to sell your computer or to give it away, you should firstly deauthorize the computer where FoldersSynchronizer is running on as registered. To deauthorize your computer, make sure it is connected to the internet, then:

  1. Launch FoldersSynchronizer and select the FoldersSynchronizer:Deauthorize Computer menu item. Hold for a couple of seconds until FoldersSynchronizer tells you that your machine has been properly deauthorized. Then your copy will run as demo, therefore with the limitations mentioned here above.

  2. Quit FoldersSynchronizer and don't relaunch it again on this machine otherwise you will authorize it again. If you need to run FoldersSynchronizer as demo on this machine or if you are going to sell this machine, remove the RegistrationFile.txt from this machine.

  3. If you need to authorize a different machine, move (or copy) the FoldersSynchronizer app to the second computer and launch the FoldersSynchronizer application there. If the second machine is connected to the internet, it will be automatically authorized at the first launch.

If you need to work on 2 or more machines but you have one only license, you can quite copy the FoldersSynchronizer application to both your machines. Then launch FoldersSynchronizer on the machine A, deauthorize it and quit. Then launch FoldersSynchronizer on the machine B and it will be automatically authorized. You can do that and viceversa at any time, without limitations.

If you lose your license
If you lost your RegistrationFile.txt and you remember your Serial Number/Purchase ID and Email, you can automatically get your license here. The serial number of the license is available on the About window when the application is registered. Your Order/Purchase ID is reported on the receipt you got from the vendor.

If you don't remember your Serial Number nor your Purchase ID, simply contact us providing us your name, surname and email you used to register the product and any other information that can help us to retrieve your record (purchase date, online store, Order ID). We will quickly email you with a copy of your license.
