iLife '11 installed and now iPhoto won't open, "damaged or incomplete".
I was unable to use iDVD after having Mountain Lion installed. I had an iLife '11 disk and I installed it. I didn't see any changes in the application folder so I used the iLife '11 disk again, found the iDVD application and selectively installed it. Now I have and iPhoto icon with a white circle crossed out and when I try to open iPhoto, I get the message, "You can’t open the application “iPhoto.app” because it may be damaged or incomplete."
I don't know what version of iPhoto I have because there are just two dashes after the "version" when I Right Click and select "Get info" on the iPhoto.app line in Finder.
I have been reading support blogs for hours last night and this morning. I am afraid to try any of the fixes because I have already caused problems for myself and my problem doesn't seem to exactly match anyone elses problem, but seems to be a mixture of more than one problem.
I have a backup harddisk that was set to the time machine before I had my computer repaired. It only backs up to Dec 2, 2013. I have not hooked it up again yet out of fear that it will start backing up and mixing old with new. I had Lion before the repair (new video disk) and when I received the computer, Mountain Lion was installed. This was last week. I specifically asked that Mavericks not be installed because I was reading so much unhappiness with it.
So - any help extremely appreciated. I am frozen.
