I'm trying to install my app from the Mac App Store now that it's been published. I'm using the same machine as the one I developed the app one. For some reason, the App Store claims "A newer version of this app is already installed on this computer." I haven't touched the version number since I submitted it so this is strange.
I've removed all references of the app from Applications, Library/Preferences, Library/Application Support, Library/Caches, /var, and Trash. I've also cleaned the Product from within Xcode.
Any suggestions?
Thanks!
To remove any unwanted update :Make sure "Check for updates" is disabled in the System Preferences. Send the app you don't want to update to the Trash. Open the Updates tab in the App Store. The update should have disappeared.
Update from the Apple menu On your Mac, choose Apple menu , then see if you have any updates available. The number of updates appears to the right of App Store in the menu. To get your updates, choose App Store. After App Store opens, click Updates in the sidebar.
I had this problem with CoBook on Mountain Lion and nothing out there seemed to work until I found this:
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
