Xcode 4.1 can't reinstall. App store says "installed"

Question

Today i update my system to Lion and try to update Xcode. After downloading from app store i get error.

So i remove my old Xcode 4.0 by this command

/Developer/Library/uninstall-devtools –mode=all

But now in app store i have the status "installed" and can't reinstall my Xcode. So what i must do?

p.s Trash is clear.

Solution 1

When I downloaded Xcode from the Mac App Store it created an Icon in launchpad called 'Install Xcode' and you're able to kick off the install from there.

My installation failed the first time and I was able to reinstall fine.

Solution 2

sudo /Developer/Library/uninstall-devtools –mode=all

sudo rm -rf /Developer*

sudo rm -rf /Applications/*Xcode.app

Download & Install "Install Xcode.app" or now just "Xcode.app" from the AppStore again, and run it.

Solution 3

Try a spotlight search for Xcode. I found an Xcode installer app in my applications folder when I did that.

Solution 4

Delete "Applications/Install Xcode" you can then re-install from app store

Solution 5

I had the same problem with other app. Deleted it and could not install again from App Store. The problem was that I had backup copy on the mounted external disk. After I have un mounted the disk with the other copy, App Store let me download the app again. Regarding to what verylastminute wrote - if Appstore can "see" any other duplication file it will not let you re-download.

I did indeed have the Install Xcode app in Applications, but it was for the previous version of Xcode. Deleting that still would not allow me to install. Finally, I just deleted xcode.app from Applications and was able to start downloading the new version.

Good tip. The crazy thing is that Spotlight found the install app, but ls -l 'Xcode' did not.

Thanks, this really helped (+1) i had missed the launchpad icon!

Please note my answer only applies to Xcode 4.1 and maybe 4.2 or 4.0. The current version doesn't even have the /Developer directory anymore. :-)

See @seano's answer too. It wasn't in launchpad for me, but found it using spotlight.

It's not anywhere at all for me. The problem is that it's seeing Xcode on my backup drive. Ugh, the App Store is a mess. Why can't I just sudo apt-get install this thing?!
