Home directory:
I found the "Home directory" on my desktop. With the new installation of Centos 7 there was a folder named Home on my desktop. I started there. Even if I tried to navigate rootwards that was as far as the GUI interface has let me with the available buttons, so I assumed that was the start.
File command:
I've played around with the file command. Among other things, it tells me which files are executable, which are shared objects etc. Among those that are executable I might find the program.
Centos Repository:
Yum comes to mind.
I'll work through the links you've gave me and install it as recommended. Though, the existing installation might interfere with the new installation.
The installation seemed fine. Everything works now.
The missing part was a file called "UnityHub.AppImage".
I executed this file with the idea to reinstall the program, but when it ran it actually opened the user interface and I could continue on the project where I've left off. The old project I created earlier was there, and I could start editing the project.
The file UnityHub.AppImage was in my Downloads folder. Either me or the computer must have cleaned it up. When I redownloaded the file I could start using it again.
I copied the file to my desktop and it still worked.
