I'm still getting this error
This worked - thanks!
You're sure that you were on 2.0.43?
I'm on 2.0.43 and I keep getting the same popup every time I start the laptop. I can see 2 files in:
GOG Galaxy Notifications Renderer.exe.lock
Gonna delete the first one and see if it occurs again. If it does I'll report back.
Deleting the first file alone did not work, relaunched it and got the popup again.
Deleted the second one, relaunched it, and didn't get the error.
After booting up the laptop again today, I got the same message again. I can see both the files are back in the same folder. Maybe a reinstall will help.
