I reproduced your problem exactly on another Windows 10 computer. “service not running”. Actually nothing about the Gear installs and uninstalls would go right, nothing ever removed by the uninstalls. Even tried Gear’s manual uninstall (which was a real pita. Seriously, they can’t make a reg file or script to do that ???), without success. I think they have some real problems with new installs on the latest version of Windows 10. But I hope you get a solution.
My Wavelab on the other Win 10 (not the new Gear installs) continues to work ok though.
