Hi. I got the bug as well. I managed to install 4.5 earlier but before opening or creating any project I deleted the earlier versions I had installed. Then when I tried to run 4.5 It just went to a verification process but didn’t run the program. Clicking launch didn’t do anything. Restarting UE4 and my computer didn’t do anything either. Uninstalled 4.5 but now when I’m trying to reinstall it the latest version appearing is only 4.4.3 Do I still have to download version to get the 4.5 or should I wait til the bug is fixed? Thanks! Can’t wait to try the new features!
