Where to see the versions of unity that you install with unity hub?

hello, I have unity hub, I had to format my computer and I do not remember the version I had, as I used unity hub with a linked account I asked myself: are records of the versions downloaded in the program kept?
I always delete the versions that I have installed when I download others. thanks

If your unity hub isn’t showing Unity installation versions you have on your hard drive, you can manually add them by using Installs-Locate. Browse to it, usually under Program Files on PCs.
If you add existing projects to your projects tab using the Add button it shows the version it was created with under it’s name. If it doesn’t find the installed version of unity it will have a warning icon, and the Unity Version dropdown will say “Select a version”.
