If there is a game installation that says Windows 32 bit, can it be installed on a Windows 64 bit computer?

Maybe. Not a great answer, I know. In my on-line searches I found that sometimes it works and sometimes it doesn't. I know I have installed 32 bit games on my Windows 10 computer without any problems at all.

So, is there any harm in trying it? I do not want to mess up my computer.

No. It will either work or it won't.

Okay, thank you!

Let me know how it works out! What game is it, by the way?

It's a puzzle game called Back to Bed that I got in the Itch.io Bundle for Ukraine . It is also on Steam. Steam doesn't mention 32 bit but Itch does. It seems to be working.

That's great! Hope you like it!
