Attention: For driver problems it is very important, that all currently available Windows patches are installed.
(Note: Usually step 1) & 4) already solve the problem.)
- Unplug all EVC devices from the computer.
- Open a Windows command-line with admin rights. (Right-click the icon)
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON

- Install WinOLS again. Activate "Force driver installation".
