Adobe Photoshop CS4 - Graphics issue

Hello all - 

I'm still using CS4 because I own it and until now it's worked fine for me. 

Recently I had my laptop stolen and had to replace it. I'm now trying to install my software on the new machine. I got a bunch of errors during installation - some programs installed and some didn't - and I kept brute forcing through installation one program at a time until I thought I had Photoshop installed. But when I went to open it (after adjusting the graphics settings so the program displays at a reasonable resolution on this monitor), and try to create a new project on a blank canvas, this is what I see. 

This is an HP Spectre x360 running Windows 10. Hardware should be more than appropriate for this software.

Any ideas on how to troubleshoot or resolve this? Thanks much.
