Is there a way to convert project to an earlier version of UE4?

Thank you very much. I have already tried that. I tried it doing it from the project itself and manually moving the files. The first gave me an error message about the “version numbers” being different, or something like that.
The second just didn’t load at all. Keep in mind that those were two new, different projects, Not the same, to make sure that the error wasn’t from the first try.
I even tried to convert the project to an older version but that didn’t work out either.

Again, thank you for your suggestion.

I wish 4.8 wouldn’t run this badly on my computer. ^-^
