How do I re-installing Xcode 4.1 for Lion?

I downloaded Xcode 4.1 via App Store to install on my system. Maybe because I had 3.x installed or maybe because of an internet glitch, I got it downloaded, ran Xcode Install, but when I tried to launch Xcode crashed immediately.

I assumed it was corrupted, since I found this in the trace:

Application Specific Information:

ProductBuildVersion: 4B110

UNCAUGHT EXCEPTION (NSInternalInconsistencyException): Couldn't load plug-in 'com.apple.dt.IDE.IDEiPhoneSupport' while firing fault for extension 'Xcode.Device.iPhoneSimulator'

}

Not seeing how to uninstall it properly, I just went ahead and deleted everything in /Developer (and /Developer.old, my previous install). I assumed I'd be able to reinstall it over the top again. Dumb assumption, because App Store shows it "Installed" and I don't know what to do to clean up and reinstall it again.

Any help appreciated!

Do you have a Time Machine backup with the old version attached to your Mac that the MAS is reading?

Ah, just figured it out. Turns out the Xcode Installer app didn't get deleted after all upon installation. It was still there when I looked through everything listed in Launchpad. I reran it, and this time it installed things well enough so that Xcode starts up completely.

Thanks for your help anyway, Dahveed.

Thanks - I had the same problem, and reinstall worked for me as well.

I experienced this when migrating my dev tools to a 2008 MacBook and upgrading to Lion. Actually repeated the process several ways and even tried re-running the XCode installer. Spotted something on another site and tried downloading and re-installing iTunes (which contains some libraries to communicate with iOS devices) and that did the trick. Just wanted to add that here in case someone has no luck re-running the installer.
