Adding in my vote for an offline installer. I work in a SCIF and there is NO option for an online driver installer. We own 4 DK1's, 4 DK2's, 4 CV1's (Which we are struggling to use) with a potential to buy thousands for our agency.
I know this post is from 2007, but in 2020 is working for someone? I'm getting an error at the end of the installation asking me to reboot the computer due an error.
Just FYI, in order to make it work I had to copy the folder "OculusSetup-DownloadCache" after the entire app was installed and before it's removed by the installer, basically, at the specific moment before pressing continue on the successful installation message. If you do the kill process procedure, it won't work.
