Updating from Snow Leopard to Mou
I have a message that said update failed error 102 when updating iPhoto to 9.4.3 in Mountain Iion. All other updates have worked. Do I have to uninstall and reinstall. iMac 21" 2.66GHz upgrading from Snow Leopard. I want to make a back up install disk but don't seem to be able to until I complete this update.
iMac, Mac OS X (10.6.8)
