Unreal Engine 4.7 Preview

Hi.

I’ve been trying 4.7.1 version on a project in my laptop for a couple of weeks and now I planned to continue working on same project in my desktop computer, where I have 4.6 version installed. After copying project files, I was about to install 4.7 preview in to continue working but theb I noticed that there is no way to download it since it seems to have dissapeared from launcher options.

4.6 editor crashes when trying to open 4.7 project, so now I can’t work on it. Is there still any way to download and install 4.7 version?

Any help will be appreciated. I would not like to be forced to work in  project on a small laptop forever!
