Can't download from App Store

A click on "Install App" does nothing. No error message, no download. I am trying to download an app appropriate for my installed OS.

I've rebooted and signed out/in at the app store. No change.

I'm editing because this appears to be the same issue. I signed out and into the app store, and am trying to update existing software.

This is the resulting error message. It references "other account" but this is the account I use, exact same ID I just signed in with.

Solution 1:

Try resetting the Mac App Store.

1. Enable the debug menu and restart the Mac App Store.

   defaults write com.apple.appstore ShowDebugMenu -bool true
   

2. Choose the Reset Application option and restart the Mac App Store.

   

Solution 2:

After struggling with the error message of "updates for other accounts", I found a solution to all of it.

The apple forums offered the solution through the debug option.

Type defaults write com.apple.appstore ShowDebugMenu -bool true into terminal and a combination of Cache Buster, Clear Cookies and Reset App did the trick.

After that, the apps were able to update. FWIW, I tried download a new app, but wasn't quickly able to find a Snow Leo app. 10 tries, and all wanted a newer OS.
