I try to download Mountain Lion in the App Store.  It gets bascially all the way through the download, and then show this screen:



The message reads:

"The application could not be downloaded.

The operation couldn't be completed. File exists"


Please help.  I am on a Macbook Pro running OSX 10.6.8.  Downloading over ethernet (not wifi), with adapter plugged in.  Have tried restarting the computer.



MacBook Pro, Mac OS X (10.6.8)

    UPDATE - I retried the download, and this is the error I got this time:


    Any help or tips would be much appreciated.

    It almost seems as though you already have the installer.  Have you checked your applications folder for it?

    Thanks Ri-dog,

    I have checked the applications folder, nothing there.


    However, I have been attempting the download again and again, and this time although I got a similar error, I was able to find a .pkg installer file of Mountain Lion in User >> Library >> Applicaiton Support >> AppStore.  When I tried to run the installer it gave me another "File can't be downloaded" error.


    You are right though, what seems to be happening is that I get all the way through the download, and something at the very end causes an error.  So now I have most of the 4.4 GB installer on my computer, but it never gets to the point where it looks like a nice application in my applications folder.


    Any help is appreciated!

    Try creating another admin account and see if you get the same results.


    Another thing which has worked for some is to boot into the Safe Mode and download.

    If you get Mountain Lion downloaded, you can make a bootable backup before installing using:


    Lion Disk Maker
