Q: how do i delete apps on itunes

open itunes, and in the left side bar, click apps. then select the app you want to delete, and right click on it then hit delete.  it will ask you if you want to delete it, and click "delete app" and then another box will come up, and reply to it "move to Recycle bin" and the app is gone. it might come back to your computer if you still have it on one of your devices (Iphone, IPad, etc.) so make sure you delete it on those sdevices as well.

itunes mac 10.6.1

I right click on an itunes app, no menu appears. i highlight the app and hit the delete key. it doesn't delete. i highlight the app and delete is grayed out in the itunes menu.

Are you looking at the "Apps" page in iTunes and NOT on your iDevice?

This page is shown by clicking on "Apps" in the iTunes left sidebar.  It should be just above "Store".  If not, check your preferences.

Thank you, yes I was looking in the wrong area of itunes.

Thanks,  this worked.
