Can I install UE 5.1 after I installed 5.3 and run either version?

Hello,
I installed UE5.3 and now I want to install UE5.1, so I can use the Twinmotion plugin. I do not see an option to add the 5.1 Engine.
Do I need to uninstall 5.3 1st or can I install 5.1 after installing 5.3 and run 5.1 till there is a Twinmotion datasmith beta plugin for 5.3. Please advise, Thanks!

hi @greenidog
In Epic Games Launcher go to Unreal ->Library

Click on the Yellow Plus + which will bring up the 5.2.1 icon

Click on the white Dropdown inside the 5.2.1 top right

Select the 5.1.1 or any version to create the 5.1.1 icon the click on the Install you will need at least a further 60DB.

Hi Jimbohalo10,

Thank you that worked! Now if I could get the datasmith for twinmotion to showup in the importer list. It shows it installed and both the datasmith and content pack is enabled and it does not show up in UE 5.1.1. UE 5.1.1. was the one available and now I am wonder if I need to go to a lower 5.0 version for datasmith for twinmotion to show up in the import list?

Please advise,
Thanks!

Hi again,

I found it as it was located on the + toolbar, so now I was finally able to import my twinmotion file.
Thanks again for fast response!
