I have Windows 10 at home and 7 at work, so I could not install Remote Play on my work PC. What I did was copy the folder (C:program files (x86)SonyPS4 Remote Play to a usb drive and then copied it to my work computer. The program launches, I can connect to the PS4. Now the issue I am having is that I get "the connection is lost" after it connects, but I think it's because I am at work.
I have a Win7 computer at home I will test, but it does look promising.
As https://www.reddit.com/user/jayr2305 stated, you can extract the remoteplayinstaller.exe using the /extract switch at a command prompt.
