FlyInside requires Windows 7 or later in order to run.
If you are running a modern version of Windows, ensure that your flight simulator is not set to run in compatibility mode.
His OS is Windows 7 and he tried to run FSX:SE with compatibility mode turned off. Of course, he allowed unknown sources in the oculus app settings.
I would greatly appreciate it if you kindly give me some advice.
His system:
Intel core i7-6700@3.4GHz
RAM 16Gb
Windows 7 64bit
NVidia GeForce GTX 1060
AsusTek H170-pro
Oculus rift CV1
