I have manually uninstalled, reinstalled, disabled my AV, run in safe mode, submitted logs to support and everything in between (numerous times). I am just about to add exclusions to windows defender (although support are not being very helpful in exactly how I do this)...nothing appears to work. Support appear to clutching at straws...looking for any suggestions to assist. It's my sons birthday in 2 weeks and he wants to have mates over to play on Oculus. I've been back and forth for 3 weeks....I am not technical at all and I'm struggling and getting no where. It's been an utter disappointment and a lot of money down the drain as we bought a properly spec'd PC specifically to use with Rift. It just says it can't update as there is not enough space....but there is?! I have 45GB of free space on the C drive and a 2TB additional hard drive. HELP!
