Guys, I've been going back and forth with tech support for a week now and they've stopped responding to me since Sunday.
Basically when I run the OculusSetup.exe it fails and roll's back. In the Oculus Setup.log file the offending line is:
[Error] [9/7/2017 11:12:23 AM] Error getting files from manifest for oculus-runtime: Unable to read manifest 'H:\Oculus\Manifests\oculus-runtime.json'.
I've tried installing on C:\, G:\ and now H:\ a freshly formated drive using OculusSetup.exe /drive=H. During installation it downloads all required files, and starts to populate the manifests folder. I see the oculus-runtime.json and mini.json files being generated. Before it failed I copied those files out to a different folder and perfomed a JSON validation on them which passed just fine. I've looked through windows system logs and did not see anything relevant.
The OVRLibraryService.log ends with success on the previous installation package as shown below

Then nothing else.
Any thoughts? I haven't seen anybody with this problem yet.
Thanks in advance!
