can I run both the free and the full version on the same pc?

hi everyone, can I have both the free version and the full version running on the same computer or once I get the full version it will replace the free version too?

You can install them both to different locations. There may be some conflict with environment variables, but I’ve seen this working before.

Really though, the full version IS the free version but with content unlocked, I do believe.

Paying for Unity PRO just unlocks features in the Unity you already have running.
