This beta won't even begin to load on my Windows 10 laptop (Version 1803. Build 17134.523). The setup screen doesn't even appear. Just a blip appears on the Taskbar (that disappears in a second or so) but nothing else? Machine is an Inspiron 15 7000 gaming system; Intel I7 64-bit, 16 GB RAM, 303GB free HD space. 4K screen.
UPDATE: Just tried it again and it was successful after I did the following:
1. Right-clicked on the installer executable and selected Properties.
2. Chose the Compatibility tab and clicked on "Change high DPI settings" near the bottom.
3. In the new screen: Near the bottom, check the box for High DPI Scaling Override. "Scaling performed by: " Choose "SYSTEM (Enhanced).
4. OK your way out of the boxes.
After that, I doubleclicked the installer executable again and it ran/installed fine. SO - what we have here is a 4K scaling issue, guys. This beta don't like running on hi-def screens
