If you're getting an error from Oculus Home when trying to install or update Rec Room, you can try the following:

• "This is commonly a permissions or security issue. You might want to try disabling anti-virus and (if that doesn't work), reinstall the Oculus app to a better folder with proper permissions (for example, something like E:/Oculus would probably work fine)." - Reference
• Restart your PC
• Ensure your graphics drivers are up to date
• Ensure all Windows updates are installed
• Uninstall Rec Room and then "Manually delete C:\Program Files\Oculus\Software\against-gravity-rec-room and C:\Program Files\Oculus\Software\swap, and they will possibly encounter Windows errors when they do so (but hopefully not). Oh and also C:\Program Files\Oculus\Software\staging, just to make sure." - Oculus Support
• If you are still unable to resolve the issue after trying all of the above steps please send us your Oculus Home logs while you are experiencing this error: https://developer.oculus.com/distribute/latest/concepts/log-troubleshooting/
• Follow instructions for 'Troubleshooting the Oculus Run Time'
• Choose 'Get All Logs' when asked how much log data you would like to export
