Coherence Mode doesn't work in Parallels 12 (I've tried everything)

[JeffB13]

I've tried everything. Coherence Mode is greyed out in Parallels 12 for Windows 10.

• I do not have an antivirus. (http://kb.parallels.com/en/121427)
• There are no other display adapters besides the Parallels Display Adapter (WDDM) that are installed.
• Parallels tools are installed properly. I've tried re-installing parallels tools in every manner outlined here: http://kb.parallels.com/112609

My setup: - I'm using a Mini DisplayPort to Dual-Link DVI Adapter to hook up to a 30" monitor. - Unplugging it doesn't allow Coherence Mode either.
Thanks for any help!

Please try uninstalling and installing Parallels Tools.
Also, please follow the steps as per the KB article. (Also applicable for other Windows)
