I am trying to get Xcode 4.5 running along side my current XCode version.
I can see alot of posts saying you just drag the .app file from the dmg to a place on your HD, but when I do that and tries to start XCode 4.5 from that file it starts an installer.
From what I have read it should simply start the program right away. Can someone tell me what im doing wrong?
Downloaded the dmg file from iOS Dev Center.
You’re doing it fine. The first-launch installer installs a couple things required for the new version (e.g. Libraries for talking to newly-supported hardware), but it won’t interfere with the workings of the previous version of Xcode. The same thing happened with Xcode 4.4 and 4.3.
