Download the launcher from here:
https://orbusvrdownload.s3.amazonaws.com/Launcher-0.81.zip
After you download it, extract the ZIP file anywhere on your computer, such as your Desktop or Downloads folder. NOTE: If you extract it to the Program Files directory (or other protected directory) then you will need to use “Run as Administrator…” to run the launcher. So we recommend NOT extracting it to the Program Files folder.
Inside the folder there is an application called “OrbusVR_Launcher.exe”. Just run this to boot up the launcher. Login with your OrbusVR account details and then the launcher will begin to download the latest game files. Once the downloads have completed and the server is online you will see a “Launch Game” button that you can press. The total filesize of the game client is approximately 2GB.
