Installed iDVD from iLife 11 and now iPhoto won't open
Despite the decree from Apple that physical media is dead, I still wanted to make a DVD of something I made in iMovie but I could not find iDVD anywhere on my 2011 Mac Mini. Since iDVD was available in the App Store, I bought a copy of iLife '11 from Amazon and installed iDVD only (everything else was greyed out, except iWeb which I deselected). Now I can no longer open iPhoto! I can't remember the exact dialog box warning, but something about being damaged (I'm away from my Mac). I ran software update and there was an update for iDVD which I installed. I've restarted, I've repaired permissions, and nothing works. I've tried holding down Option while opening iPhoto but it still says it's damaged or incomplete.
