How do I make 5.3 projects 5.3.2?

Every time I open my 5.3 project, it tells me I need to make a copy because it was made in an older version (it was not). When I do that, however, it removes the vast majority of my project. Please help!

Have you tried switching the version via the uproject file? If you right click on the uproject file in a file browser you there should be an option “Switch Unreal Engine version…”. From the dropdown select the version you want.

Thanks, but now when I open it, it says it needs to be ‘rebuilt from the source manually’. Do you know what this means and/ or how to do it?

It works now! Thank you for your help!
