Start, Stop and Restart on services are not active. What to do?
After I've looked on the available websites found through Google, I come to the conclusion that Stormshield VPN works only versions of Windows up to Windows 8. There is nothing regarding the Windows 10 availability, but because the software is still available and the developers can be reached as well, I believe a new update will be provided to you in the months to come to support Windows 10 OS.
