Re-Installing GarageBand from iLife '11 DVD (Guitar Tracks Issue) Due to an issue regarding the creation of Guitar Tracks in GarageBand '11, and that none of the reported fixes (here and here) have worked, I am looking to re-install.  However, I don't appear to be able to re-install just GarageBand '11 from my iLife DVD.  I have navigated to the 'Customize' part of the installer, however it greys out the tick boxes for iLife Support, iPhoto, iMovie and iDVD (both skipped by default), and GarageBand.

I don't want to re-install iPhoto, nor anything else other than GarageBand and because I have bought a retail version of iLife '11 I don't think I can download from the App Store.  Given that an App Store download was one of the known causes, then this wouldn't be appropriate anyway.

Of course, if someone has a proven fix for my problem other than those mentioned then I would also find that acceptable :-)

Thanks
You might try installing Pacifist - it allows you to get inside apple's installer packages and install individual items
