Installation guide

Hey! Thanks for choosing Synergy. We're glad you're here and we hope you enjoy the product as much as we do.

This is a quick and easy guide to help users new and existing to install Synergy on their computers. So if this is you, then you're in the right place!

Quick note: Before we start, let's jargon bust.

Anything referred to as your Server computer will be the main computer that is physically connected to your mouse and keyboard.
Next, anything referred to as your Client computer will be the computers that the mouse and keyboard are being shared with. 

Step 1 - Installation

  • Step 1.1: Install Synergy on both the Server and Client computers.  
    • Head to the Download page on our website. Here you will be asked to log in.
    • Once logged in, you will select either 64-bit or 32-bit depending on your system type. 
    • Click 'Run'
    • This download should take less than a minute, depending on your connection speed.
    • Now repeat this process on the Client computer
  • Step 1.2: Setup Wizard - Server computer
    • Now a Setup Wizard should appear that looks like the below

    • Press 'Next' until you have the option to click 'Install'. Click this, and allow the app to make changes to your device.
    • Press "Finish" when the installation has been successfully completed.
    • Finally, select your chosen language.
  • Step 1.3: Activating Synergy
    • Select 'Server' and click 'Finish'.

    • You will now be asked to enter your License Key. Head to the Synergy website, click 'Account' and you will find your unique License Key.
    • Copy and paste your License Key into the given space and press 'OK'
    • You have now activated Synergy! 
  • Step 1.4: Setup Wizard - Client computer
    • Now move onto the Client computer and repeat Step 1.2
  • Step 1.5: Activating Synergy - Client computer
    • Select 'Client' and click 'Next'.
    • Repeat the remainder of Step 1.3


Step 2 - Labelling your computers

Now we need to rename your computers to make Synergy configurations easier to manage.

  • Step 2.1: Naming the Server computer
    • Navigate to Settings by clicking [Edit] -> [Settings] or, if the link to Settings in the below screenshot is visible to you, click that instead


    • Change the Screen Name field to something easier to remember like 'work-laptop' and press 'OK'

    • Note: Your screen names should not contain any spaces.
    • Next, we need to restart the application. You can do this by pressing 'X' or 'Start', and reopening the app.
  • Step 2.2: Naming the Client computer
    • Repeat the same steps as Step 2.1 but this time, name your computer something different like 'home-pc'.

Step 3 - Connecting the computers

  • Step 3.1: On the Client computer, we need to try both of the IP addresses to see which is the best one to use.
    • Manually type in the first IP address into the Server field. In this case, we are using
    • Hit 'Apply' and watch the Log box to see if a warning appears.


    • If a warning appears, it will look like the below screenshot.


    • If you get this warning, then you just need to try inputting the second IP address.
    • When you do this successfully, the Log box on the Server computer should start populating with new lines
  • Step 3.2: SSL Fingerprint
    • On the Client computer, the message below should appear with a long string of numbers and letters

    • You should compare this string to the SSL Fingerprint displayed on the Server computer

    • If these match, press 'Yes' on the message displayed on the Client computer.

Step 4 - Configuring Synergy

If you see a warning message in the log, don't worry - this just means that we have to finish configuring Synergy!

  • Step 4.1: Configuring the Server computer
    • Click 'Configure Server'

    • Another window will pop up like the below. Here you will drag the top right icon into a box that best represents where your Client computer sits on your desk.
    • In this example, the Client computer is situated on the right-hand side of the Server computer.

  • Step 4.2: Configuring the Client computer
    • Now, the new icon should have the label 'Unnamed'. We need to change this!
    • Double-click on the new icon and it will display the window below:


    • In the Screen name field, you will input the same name you gave the Client computer in Step 2.2 and press 'OK'
    • In the next step, press 'Apply' on both the Server and Client computers to confirm the changes

Installation complete!


Enjoy using Synergy!
