Problem with version

I have downloaded an example of the tracking vehicle to learn how to do it, i need to develop tank physics for my game project. But there’s one problem - it is 4.12. I tried to load it with my 4.22 UERedactor, but it just starts to load something big and then just crashes, 'cause my computer can’t stand loading process, that takes up 4GB in my RAM!

So, you’ll say: there’s a way to convert project from 4.12 to 4.22. Not so fast, i tried to do that, but the same problem appeaers.

Is there a way to download later versions of Unreal? Or, maybe, fix this problem? If you have any ideas, then share it, please!

I’ll also leave a link to this TrackedVehicleProject. Be carefully, if you see it stops loading when you launch the .uproject, close your editor with TaskManager (On my computer, it stops loading on 45%).

Sorry, i thought earlier versions of Unreal, and it’s advisable to download 4.12.
