Actually i just found out that you don't have do choose between the sdks. You can just simply stop 0.7 and run the old 0.5.
Deinstall 0.7 reboot and install 0.5 (ignore all errors)
Save the C:\program files (x86)\Oculus\Service\OVRServer_x86.exe to a different location
Install 0.7
Copy OVRServer_x86.exe back where it came from.
Rightclick, go to properties, then compability an set ist to windows 8 and run as administrator!
Reboot
Make a batchfile containing
net stop OVRService
"C:\program files (x86)\Oculus\Tools\DirectDisplayConfig.exe" off
"C:\program files (x86)\Oculus\Service\OVRServer_x86.exe"
Name it SDKold.bat for example
and run it as administrator!
A shell should open an your Rift should become second screen. (if not go to your screensetting and look if you have to extend your primary screen manually)
Don't close the shell!!!!!!
Start ED and change Grafic settings to secondary monitor and 3d to Rift (as normal)
Play and have fun!
To switch back to 0.7
close the shell
and use a second batchfile containing
net start OVRService
Name it SDKnew.bat
run it as adminstaror
and you are good to go again
Hope that brings back the all Windows 10 Commanders
Fly save!
Thats great, Thank you. I will try it later today.
