Hey there,
new to vorpX and didn´t try it for now but I bought it yesterday and tried to install it under Windows 10 x64. Installer started but did not finish. I registered the program but neither tested it, nor did I install it a second time. I left the installer running for close to 2 hours but it didn’t close in the end. Can report back it things worked without installing a second time. I have installed Virtual Desktop as well for my Quest 3 but did not close the desktop streamer. Unfortunately I didn´t close the streamer. So may be it interfered with vorpX ? I do not know.
