Xcode 4.2 on Lion-- App store thinks the app is already installed

Question

Is any one seeing the issue I m facing. I am trying to upgrade to Xcode 4.2 on my Lion and the app store says it is Installed.

I had a developer preview of 4.2 may be that's the issue. I went into the launchpad to see if the Install Xcode was there. Yes, it was present there but it was for 4.1.

Any one know the way to install the Xcode 4.2 on Lion?

Thanks

Yep, I had the same problem. Here's what fixed it for me:

1. Go to the Applications folder and delete Install Xcode.app.

2. Go to .Trash in your home directory, and manually delete Install Xcode.app. I did this in Terminal.app by typing the following:

   sudo rm -rf Install\ Xcode.app

You could of course combines steps 1 and 2 by executing the sudo rm command right in the Applications folder, but I felt a little safer doing it this way.
