We are aware of an issue in Synergy 1.10.3 where the background service fails to start.
Service "Synergy" (synergy) failed to start. Verify that you have sufficient privileges to start system services.
We suspect that this issue is caused by the installer not providing the correct VC++ redistributable.
Solution: Install the latest VC++ redistributable from Microsoft.
