How to reinstall or uninstall Synergy 3

Updated

Written for Synergy 3 (v3.7.2), checked 3 October 2026.

Product: Synergy 3
Operating system: Windows, macOS, and Linux

Reinstalling after a full uninstall fixes many installation problems, especially after upgrading from an earlier version.

Before uninstalling

Try resetting your Synergy 3 settings first; it fixes most problems with an installation. If your problem is still there afterwards, continue with the steps below. For the reset steps, see: Local settings in Synergy 3: login screen, beta updates, appearance and reset

Reinstall Synergy 3

  1. Uninstall Synergy 3 with the steps for your operating system below, including removing its config files.
  2. If Synergy 1 or Synergy 2 is also installed, uninstall it too. For Synergy 1, see: How to reinstall or uninstall Synergy 1
  3. Restart your computer. Important: don't skip this before installing again.
  4. Install Synergy 3 with the guide for your operating system:

Uninstall steps

Windows 10/11

  1. Open Settings > Apps > Installed apps (on Windows 10, Apps & features)
  2. Look for Synergy on the list
  3. Click ... next to it
  4. Click Uninstall
  5. Click Uninstall again to confirm
  6. Click Yes if Windows asks whether to allow the app to make changes to your device
  7. Remove config files (see the end of this page)

macOS

  1. Quit Synergy 3 from its icon in the menu bar
  2. Open the Finder
  3. Go to Applications folder
  4. Drag Synergy to the Trash
  5. Remove config files (see the end of this page)

Linux

Use your package manager to uninstall Synergy 3. The package is called synergy.

APT (Ubuntu and Debian)

Open the Terminal app and run the commands:

sudo apt remove synergy
rm -r ~/.config/Synergy

DNF (Fedora and Red Hat)

Open the Terminal app and run the commands:

sudo dnf remove synergy
rm -r ~/.config/Synergy

If you have edited the DNF config file to stop Fedora downgrading Synergy 3, first remove exclude=synergy under [main]. The edit is described in: Prevent Fedora from downgrading Synergy 3

Pacman (Arch Linux and Manjaro)

sudo pacman -R synergy
rm -r ~/.config/Synergy

Flatpak

sudo flatpak uninstall com.symless.synergy

Other package managers

Please read the documentation for your package manager, and follow the instructions to remove a package. If you're having problems, please contact us

Removing config files

For a more thorough uninstallation, manually remove the config files which are stored on disk:

  • Windows: C:\ProgramData\Synergy
  • macOS: ~/Library/Preferences/Synergy
  • Linux: ~/.config/Synergy

If Synergy 1 is also installed on the same computer, it keeps some of its own settings in the same Windows and Linux folders, so removing them resets Synergy 1 too.

If you need help finding and removing the config files, contact us.
