I’m subscribed but when i try to download 4.5 preview it says “Subscribe” and when i click it it takes me to the unreal engine website. My subscription is active. Why is it doing this?
I have the exact same problem. I’ve never had this problem with any other preview.
Yeah it shows up for me in the launcher, but only says “Preview” with a subscribe button, it does not actually say what version it is (although I think we can assume 4.5 preview) 
I’m sure, they’ll fix it soon.
My guess is they want to wait and launch in an hour when the weekly stream goes live. 
Hi all,
This is a known that we’re currently working to get fixed with the Launcher at the moment. This is something that we’re not prepared to release just yet and should not be showing. This should be resolved soon.
Thank you!
Aww i subscribed just last night so i can download the preview. When will the preview be available?
Hi gotgrassct,
We can’t give you an exact date at the moment, but it will be soon. Please bear with us.
Thanks,
TJ
The preview is now live through the Launcher.
Thanks . I’m downloading it now.
Thank you very much, !
Yes, I couldn’t download preview either. I re-downloaded the latest PC built and reinstalled it, but the red icon in my library is not showing.
Edit: Sorry, it’s pretty late here. What I did do, was click on add new engine (add slot), then from there, pressed the arrow down, and selected “preview”. It didn’t show preview number (as for the new 4.5), but it did work for me at the end, and I was able to download it.
Man, what a difference!
Thanks guys.
The is back. It says subscribe for me now but I know it was fine few days back but I didn’t download it back then.
There was an error with our server over the weekend that prevented users from downoading the engine. It should be fixed now - check again and try to download the engine.
Thanks,
Jonathan
