There is no message when I click or hover over it can someone help?
Here are my system spec’s in case they are required: (I have DirectX 12 installed and working)
Hello,
I’m sorry, I don’t quite understand the issue you are having. When you click on “Install” beneath one of the engine version, does the launcher give you any feedback?
No, at that time it didn’t do anything at all. So after about 4-5 days I tried again and I was able to install 4.9.2 I haven’t tried the others yet. So I’ll see how it goes then and update you.
Similarly to Leebowitz, I’m not quite sure what the issue is? I know that this may sound somewhat condensing but do you have enough space to install the engine?
Alternatively, you could attempt to build the engine from source which is a little more difficult but you’ll learn something in the process. Epic have released a comprehensive guide here.
No I have over a TB of space left. I’ll check out the guide, thanks! 
Not a problem, let me know if you have any more issues and I’ll my best to help you. Especially considering you’re doing it for a college course (like myself).
Excellent. Please do!
Hello Primordial21,
Any update? Have you had a chance to try the other engines?
Yes 4.9.2 works like a charm :D, I’ll be installing 4.10 soon in the next week or two as our collage updates the computers then. I’ll post an update as soon as I try to install it.
Good news, 4.10.4 works!! However on installation I had an error 0 or something, I restarted epic and it installed properly. So far it seems to be working but as soon as a problem arises I’ll let you know.
