Reinstalling or uninstalling

Updated

Written for Synergy 3 (v3.8.4) and Synergy 1 (v1.22.3), checked 20 October 2026.

Operating system: Windows, macOS, and Linux

Reinstalling after a full uninstall fixes many installation problems, especially after upgrading from an earlier version. Uninstalling keeps your settings, so remove them too if you want a fresh start.

Before uninstalling

Try resetting your 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: Resetting your settings and finding the settings files

  3. If Synergy 2 is also installed, uninstall it too.
  4. Restart your computer. Important: don't skip this before installing again.
  5. Install it again with the guide for your operating system:
