Going through a nightmare with email support lasting weeks. I've read every thread here I could, but here is the fast "whats up". Unit worked fine, then next day no video. Support thought the headset died, so sent me a new one. Same issue. Uninstalled Oculus and now can't install. Here is the log and below is where I believe the problem lies.
I'm a Systems administrator for last 10 years, and I was pretty stumped. Support also was zero help in regards to telling me what my log meant. But I took my last ditch effort and reset the PC to factory defaults using windows 10. That resolved all my issues, I can now install and play games.
Same issue here. Installed Oculus and told it to use a different drive for applications (G:). Queued up some demos and free packages and purchased the boxing game. Came back to nothing installing only to find out C: was full. Tried to move the software using VR Backupper and the store wouldn't work, so I tried to reinstall. Fails at Dawn.Setup.SetEnvironmentVariablesStep each time. Went through the event viewer and found issues with DCOM permissions. Changed each one that popped up. Still fails. This isn't a machine that is solely used with Oculus, so I have Origin, Uplay and Steam all setup using a separate drive. I am going to hate having to reinstall Windows just to get another shot and THEN reconfiguring the gaming services, and having to trigger an install on each and every Steam game i have installed from the last few years.
Oh NO NO! I am having the same problem. I really would rather not reset my machine to factory (I'll have to look up if it can be done without a physical Win10 CD).
Anyone ever get this fixed. My Oculus is brand new and I'd hate to have to return it
I'm now getting this issue after trying to move my install directory and failing. Figured I would just have to reinstall Oculus from scratch and now I'm unable to install it at all. I've tried completely clearing my registry of anything Oculus related, as well as uninstalling Microsoft Visual Redistributable 2015. No luck.
I've just encountered the same issue. I was having a different issue and figured uninstall and reinstall would solve the problem. Now I can't install! "Install 'Dawn.Setup.SetEnvironmentVariablesStep' failed." with a "System.NullReferenceException".
