xcode 4.3 installation for iOS 5.1

Question

Have just upgraded my iPhone to iOS 5.1 and found out that xCode 4.2 does not recognize the phone anymore. Then I proceed to download xCode 4.3 from App Store. The download was 1.5+ GB and took a few hours. When I came back to check the download, App Store says it is already installed. But my xCode is still 4.2 and the 5.1 iPhone is still not being recognized.

There is a "Install Xcode" icon in my Applications folder so I tried that. The installer ran for quite a few minutes and seemed to have installed a new version. But the xCode is still 4.2 after all.

So what should be done to bring up Xcode 4.3 if it has already been downloaded or even installed ?

(OS X version : 10.7.3 Lion)

Answer 1

How did you try to start Xcode ? If your shortcut referres to /developers there might still be the old version. 4.3 should now be under /applications
