App Store offers update, but says it's already installed

The App Store is offering me an update to Window Tidy, and the version number is in fact newer than the version on my Mac, but while the App Store icon in the dock shows the update available badge, the store lists the update as installed, so I can't download the update. This is the problem with cloud computing. It works great when it works, but when it breaks, I can't fix it myself. Grrr...

Mac Pro, OS X Mountain Lion, 8 x 2.8 GHz 10 GB RAM, Radeon 4870

Hello again Gary,


All I can say is that it the App has not been fully deleted. There is a copy lurking somewhere. Do you have a back up somewhere?


Check out Spotlight or EasyFind (Download EasyFind for Mac - File, folder, and text contents search tool. MacUpdate.com) Get it here, free. The last one I did was iBoostup. Easy Find found one copy and several pieces of info, all of which gave me the same situation as you have.

Hi Gary,


At last!


I cannot remember specifically about Time Machine now. But other elements do need to be removed. I seem to recall about six different things, though I can't recall exactly what they were. I think it was whatever showed up in Spotlight.


I just hope the extraordinary long maintenance shut down today was in part, to do with resolving this problem.

I have the exact same issue with the exact same app. Window Tidy 1.2 installed, 1.3 available for update, shows already installed, no update button, no way to clear it or the badge. I logged out of the App Store and back in and no change. Also, I have an iMac and a MacBook Pro, both on OS X 10.8.2, one has this issue and one doesn't.


Isn't there a .plist file somewhere we can delete to make the App Store start over fresh?

You've clearly made some progress with the reinstall then. It's not unknown for the badge to go away without warning; perhaps after a restart. It's taken a while so do let us know how things end up.


Incidentally, I've now remembered where my extra app copy was located. I'd made an alias of the original app as I usually do with those apps that are not updates of iMac apps. That's what the App store found when it stopped me from reinstalling.
