I have a 5 day old ( imac 20" aluminum) running 10.5 I'm trying to install Google Earth and I get this: "/users/myname/Desktop/pqc088ap.exe could not be saved, because you cannot change the contents of that folder. Change the folder properties and try again, or try saving the file in a different location." I've repaired permissions. I've logged in as administrator and gone to that folder but was not allowed to take any action with respect to that folder. I've removed an old version of Google Earth that was copied over from my ibook. Any suggestions? THANKS!
