I had this in windows 7 and recently after about 4 months of windows 10 its happening again.
Launch iCam source, camera not activated. Mouse over to icon in taskbar. Icon disappears.
Checked for log files, none are created.
Rebooted- same thing
Reinstalled-Same thing
Ran the registry edit tool on this forum, no change.
This is a fresh, stock install of windows 10 ( only purpose is to run icam)
I fixed it before by running some command but I cant seem to find it.
Any help would be greeaat!
