The iPhoto Library is locked, on a locked disk, or you do not have permission to make changes to it. iPhoto can try to repair the permissions.

Have you moved the library from its default location in the Pictures folder, for example to an external drive?

Try the following:

1 - launch iPhoto with the Command+Option keys held down and rebuild the library.

2 - Run Option #4, Rebuild Database, followed by Option #1 if needed.

How do you do this, for iTunes, on PC? What function keys do you hold down?

The iTunes for PC forum is here:

https://discussions.apple.com/community/itunes/itunes_for_windows

You do it on your Mac. Hold down those two keys (Command/⌘ + Option/Alt) and launch iPhoto either from the Dock or by double clicking on the application in the Applications folder.

You don't - iPhoto is not available for the PC

THis is the iPhoto for Mac forum

If you have a question you need to post in the correct forum

Similar problem but not quiet the same:

Please bear with me as I am very new to this subject.

1: Using a MacBook Air OSX 10.7.5 and it is WiFi connected to a Time Capsule.

2: Overnight I have done a complete back-up. Checked the data files and all correct.

3: I can open the files on the TC except for the iPhoto Library as I want to check visually that they are there. All 2,388.

4: The iPhone Library on the TC will not allow me to look in.

5: the iPhoto Library on the MBA allows me access and I can view etc all the 2,388.

Q1: So why can I not look into the TC's iPhone Library? Or how do I open that library so I can look in?

Q2: how can I export data back from the TC to the MBA if ever I needed to do that?

Thanks for helping out a virgin in these matters.

Edit:

Sorry - item 4 should read iPhoto NOT iPhone.

Q1: Short answer: Simply, you can't. The way to test a back up is to restore it.

Longer answer: the first time you back up an iPhoto Library to TM it makes a copy of it. Thereafter it only records the changes. So, to restore you need the first back up plus the record of the changes. So TM puts the bits back together for the restore.

Q2: http://support.apple.com/kb/HT4927?viewlocale=en_US&locale=en_US has the details.

Thank You Terence

I have followed your link and seen what to do.

The next test is to see if I can execute those instructions without incurring a disaster :-))

Linc, I am having this problem as well. Today I attempted to copy my iPhoto Library (69G) to an external HD but instead it moved it. Now, I am unable to move or copy it back because my MacBook Air doesn't have enough space for it. I am unable to open iPhoto since I can't get past this problem.. How do I fix where iPhoto is looking for the library?

This is a totally different problem and you need to start a new thread for new problems with all the details about your system and your problem

You tell iPhoto where the library is by launching it while holding down the option key and using the select library window
