Hi i already did it.Im already running it in admin mode.But it keep saying: Unable to set straps error 31 , You have to run PhoenixMiner as admin... (IOMap64.sys is not missing)

How can i fix this

I did not open the second properties window, as you have in the screenshot ("change parameters for all users"), I installed only one checkbox as in my screenshot. Don't know if it matters or not.
In my rig 1070 ,1080 (with strap 2) and RX470 4Gb work together.
If it does not work, you can try to change the properties of not the exe file, but the shortcut (also run as administrator), but then you have to start it only manually, because Windows 10 will not launch the shortcut from autorun.
