We are aware of and actively investigating an issue impacting ability to access Rift software. Our teams apologize for any inconvenience this may be causing you and appreciate your patience while we work on a resolution. We'll share more updates here as we have them. Thanks.

Update:
Hey everyone - This is an issue with our software certification that we're still actively working on. For security, we use a certificate to ensure that the software you receive actually comes from Oculus. That certificate has expired, and we're looking at a few different ways to resolve the issue. We’ll update you with the latest info as available. We recommend you wait until we provide an official fix. Thanks for your patience.

Update #2:
Hey everyone - We're still working hard to resolve the cert issue. We're in the process of integrating an updated cert. Unfortunately, pushing the update out to affected users has some added complexity, as the expired cert blocks our standard software update path. We're working through the options now, and we expect to have more details to share later this evening.
