Install Fail, Windows 10. Oculus used to work...

[icrosson]

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.

[Debug] [3/24/2017 2:27:21 PM] Install 'Dawn.Setup.CreateRegistryKeysStep' succeeded.

[Error] [3/24/2017 2:27:21 PM] Uncaught exception!

The one environment variable i have for Oculus is C:\Program Files (x86)\Oculus\Support\oculus-runtime under Path.

No idea if that is the issue for these people?  I would have thought Oculus Support would have pointed it out if that wasn't being entered, it may have nothing to do with that.  Take a look once you've finished the install?

Did this one get sorted in the end @icrosson

Hey all, I just posted a new discussion about this. I wasn't getting the same error in the log as described, but here's what ended up being my problem:

PC was joined to a Windows Domain. Once I left the domain and used a local account, I was able to complete the installation. I am an Admin on the domain so permissions weren't a problem... no group policies inherited.

Hope that helps!

I'm having the exact same problem. Obviously I'd rather not have to do a complete OS reinstall to fix this, did anybody find a solution? I'm not on a domain by the way, so that's not my issue.

Having the same issue, can't find a fix. I've got a 500 dollar paper weight now.

I believe I have the same issue.
 Install 'Dawn.Setup.SetEnvironmentVariablesStep' failed.

I was facing the same error message as you. The SetEnvironmentVariablesStep got me to think maybe there's an system environment variable that I'm missing on my computer (hence the Object reference exception) ?

I don't know many environment variable, in fact I'd say I know of just one : PATH. Guess what ? It was missing. Added it (with value C:\Windows) and voilà ! Installation finished without a glitch.

The Java website has a good list of steps for many different OS as to how to add / modify the path variable, go take a look.

tldr; add PATH system environment variable and you're good to go.

I just want to confirm that homerggg's solution worked for me as well!! (Thank you homerggg!!!!).
