I have no intention of ever using Hyper again but I did attempt to install 3.0.0 to see if anything improved just from a pure curiosity standpoint.
After running the setup program, it opens a green rectangle that animates. I can only assume that's the installer, except it doesn't let you customize where it gets installed to or anything like that. After 5 full minutes of animating without ever providing a UI hint that it's doing something (on an SSD), I killed the task. I guess I'll never know!
