I have a problem about Genymotion after updating my OS to Windows 10, fistly it did not open with this error: Virtualization engine not found. Plugin loading aborted. Also u
Start Genymotion 2.5.3 in compatibility mode with Windows 8 - it solves the problem for me. VirtualBox 5.0.0 r101573 and Windows 10 Home (all for x64).
