(Ignore the fact that it says “Welcome to the OrbusVR Alpha”, that is the correct Launcher).
Once you download the Launcher, extract the ZIP folder to a place on your computer (e.g. your Desktop). We do not recommend putting it in your Program Files folder, or you may have to run it as an Administrator.
Once unzipped, run the OrbusVR_Launcher.exe file in the root directory. Then login to your account and the game will download. It’s approximately 3.5 GB in size.
Note that we may have to do another patch tomorrow morning, so be sure to run the Launcher early if you want to hop in right when the Head Start begins.
If you have any questions, please just let us know. Thanks!
The final patch is now out for the Head Start. Just restart your Launcher to get it. It’s about a 300MB download total if you already had downloaded the “main” patch. I’ve updated the link in the original post with the new alternate download location. Thanks!
