Hi! What mistake did you make? VR Desktop streamer app can be installed like any other Windows app, from here https://www.vrdesktop.net/ . This support page is to help with setting up and installing SideQuest. Since your question is about a specific VR app, if you can't solve your problem or have an issue setting up Virtual Desktop, I recommend reaching out to the devs! You'll find the button "Message Developer" under "User Reviews" below -->> https://sidequestvr.com/app/16/virtual-desktop Have a good day!
