I have 4k 3840x2160 display and this is how I fix it.
1. Right click the installer and select properties.
2. Click on compatibility.
3. Near the bottom should say. Change high DPI settings (click that).
4. Bottom should say High DPI scaling override. Click that box.
5. In drop down (same area) choose system (enhanced).
6. Run installer. You will see everything as normal
Works for me and I really hope it works for you and anyone else having this issue.
Happy new year everyone.
