Question Unity3D installed, successfully used and closed. Now how to open it again?

Hello Guys,

I'm running a brand new Centos 7.

I've downloaded a UnityHub file from the Unity website, and installed it.

Through the UnityHub interface I've installed Unity3D.

Installation was complete, I've noticed there were no shortcuts created...

After completed installation I've successfully ran Unity through the UnityHub interface that was still open.

Unity3D Editor worked perfectly with the whole IDE and 3D views and all. Great.

I closed the editor, and UnityHub also closed automatically.

Now I want to use the editor, but where do I find it again?

I've used the standard installation directories for installation.

Here's what I've tried:

In the following directory:


I find:


Which one do I open and how? Or is it located elsewhere?

I'd also like to create a desktop shortcut.

Any help would be appreciated.

That's not a complete path. Do you mean /home/Unity... or is that partial path somewhere else, such as /usr/bin/Home/Unity...

The file command will tell you what kind of file that you have.
file /usr/bin/dillo
/usr/bin/dillo: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/, BuildID[sha1]=88bc04eec3ab0485d0356fe72f58ba8a732c7eec, for GNU/Linux 3.2.0, stripped
Wasn't the software in Centos's repository? If you install software outside of your package manager you are going to have problems.

Read the docs

I don't know what the executables name is to launch that. If you think that the executable has unity in the name then you may try for example
find / -name unity

Hi, thanks for the reply.

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.

When I get stuck, I'll come back here.

Here's an update:

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.

The problem has been solved.
