No engine installed

I’ve recently purchased the engine and each time I run the launcher it removes all previous versions of the software and when l re-install it…it installs but be l’ve got no engine. I’ve done this several times as well as restarting my computer to see if that would’ve changes anything but it still says no engine. Is there a way to fix this issue?
