Every once in a while, when I start Synergy on Windows, I get this message:

failed to init synrgyhk.dll, another program may be using it

How can I resolve this? The only workaround I've found is to restart the computer, but is there a better fix?

  1. Download Process Explorer
  2. Run it, and search for synergy by clicking on the little binoculars
  3. Kill all processes using the troubling dll (synrgyhk.dll) - be careful here to not kill anything important
  4. I had to kill a process called splwow64.exe that had a handle on that dll for some reason, and everything worked great after

Another note, I was experiencing problems after a while again, but realized the batteries in my mouse were dying this time! –  capcom Oct 28 '12 at 1:40
You can also try stopping/starting service in Services, and reset your settings (it's in Regedit, search for it.) With all these three, I managed to fix some weird issue... (no specific error, it just died on me.) –  Shiki May 19 '13 at 11:34
In my case it was google chrome... –  Vlad Spreys Oct 17 '13 at 1:16

I couldn't find a solution from the synergy Q&A's site, but I found it here. Run services.msc and restart Synergy service. It should allow you to start the server now. Thanks Shiki for the suggestion. I, however, didn't need to reset the configuration in the registry. I'm thankful for that since my password is 30 digits and I don't remember it.

The following solution worked for me on Windows 7. I received the following error in Synergy:

INFO: Synergy 1.5.0 Server on Microsoft Windows 7 x64
ERROR: failed to init synwinhk.dll, another program may be using it
INFO: restarting your computer may solve this error
FATAL: failed to start server: unable to open screen
ERROR: failed to launch, error: process immediately stopped
INFO: backing off, wait=2s, failures=1

Shiki was correct. I would have commented instead of providing a new answer, but I don't have enough karma yet.

Blockquote "Solution: 1) Go to Run, type services.msc 2) Stop the Synergy service and start it again. 3) Start Synergy app and voila! No need to restart PC."

Just download: Unlocker, and navigate to the installation folder of Synergy. Right click the synrghyk.dll, choose Unlocker and kill all processes with it. Then it should work fine.
