Xcode 4.1 cannot reinstall. The app store says it’s “installed”

Question

Today I upgrade my system to Lion and try to upgrade Xcode. After downloading from the app store, I get an error message.

So, I delete my old Xcode 4.0 with this command

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

But now in the application store I have the status “installed” and I can’t reinstall my Xcode. So what should I do?

ps Trash is clear.

Answer 1

When I downloaded Xcode from the Mac App Store, he created an icon in the start panel called “Install Xcode” and you can start the installation there.

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

Answer 2

sudo /Developer/Library/uninstall-devtools –mode=all sudo rm -rf /Developer* sudo rm -rf /Applications/*Xcode.app 

Download and install "Install Xcode.app" or just just "Xcode.app" from the AppStore and run it.

Answer 3

Try searching for an Xcode spotlight. I found the Xcode installation application in my applications folder when I did this.

Answer 4

Uninstall "Applications / Install Xcode", then you can reinstall from the application store

Answer 5

I had the same problem with another application. Deleted it and could not install from the App Store. The problem was that I had a backup on a mounted external drive. After I installed the disk with another copy, the App Store will download the application again. As for what verylastminute wrote - if the Appstore can “see” any other duplication file, it will not allow you to reload.

Answer 6

If you moved the Install Xcode file to another location, and even if you renamed it, Spotlight still shows that it is in both the new location and in the applications. You need to remove any duplicates that you may have made from the file before the App Store allows you to download it again.

Answer 7

open terminal window

 cd /Applications sudo rm -rf Install\ Xcode.app 

After that you can reinstall

I had a similar problem - clicking Install on the Mac App Store did absolutely nothing. No error messages, no download, no installation.

I had to do all of the following to get the Xcode installation:

 rm ~/Library/Preferences/com.apple.appstore.plist rm -r ~/Library/Saved\ Application\ State/com.apple.appstore.savedState rm -r ~/Library/Caches/com.apple.appstore rm -r /private/var/folders/*/*/*/com.apple.appstore 

Then I deleted the existing '/Developer/Xcode.app' and the existing '/ Applications / Install Xcode.app' from the previous version. Even then, it did not work until I restarted my car!

Answer 9

I had a similar problem. I solved this by creating another administrator account on the computer. Then I installed Xcode using the new admin account.

Answer 10

You have not installed Xcode yet. . This is confusing, especially when you try to upgrade from Xcode 4.2 to Xcode 4.1 on Lion, but since the transition to the Xcode App Store is installed, you “install” the installation application, which then needs to be run to install xcode.

You have installed "/ Applications / Install Xcode.app"

You need to run this to actually get "/ Developer", gcc, make, etc.

Answer 11

A simple solution: in the App Store, instead of switching to updates or installed applications, simply go to the "Purchased Applications" page. On this page you can update Xcode.

Answer 12

After I tried all the suggestions from this and other forums, I finally was able to solve the problem as follows: I went to the App Store Store menu → View My Account, and only there I saw Xcode as available with the Install button. Hope this helps.
