Made a Boo Boo can I fix it?

Kia ora

I was trying to do some stuff on another earlier version so I remove the 4.11 preview thinking I’d go get it when I was ready do realising that remove
di just that, now I’m reald I can find it to download it. Can I fix this please?

Open the launcher
Go to libary
click on " add version" or “add engine”
search for the version you want to
let the magic installer do some boo boo magic :3

Thank you, it cam back as an option when I restarted UE4
