I originally installed the vive setup software on windows 7. It launched fine and I got almost all the way through the setup for the cosmos till I got an error at the room setup part. So I installed windows 10 as required. Tried to run the setup again and got the 210 error. Restarting the unit didn't work so I tried to uninstall/reinstall and now it doesn't install right. Viveport doesn't do anything and the vive setup app is not there at all. Also reinstalling only took like a minute instead of several minutes like it did the first time when it worked. Thanks!
