    Brazil: same error "The product distribution file could not be verified. It may be damaged or was not signed." Fixed turning off X6 AND deleting 'com.apple.appstore'. Thanks to everyone.

    Tried all of the fixes in this thread. NOTHING worked.  My computer no longer works at all and it erased my virus softare.  Apple jumped the gun and released garbage again!!!

    I have searched for com.apple.appstore and it is not on my computer, erased my virus software and now it does nothing.  Next time I think I will wait a couple of years till they get the bugs worked out.  Maybe they should not release it until it is ready.

    I don't get any other message such as you speak of in the folders etc... just this:

     

    The product distribution file could not be verified. It may be damaged or was not signed

    If you have Virus Barrier installed, temporarily disabled it:

    http://support.intego.com/entries/21185723-how-to-temporarily-disable-turn-off-v irusbarrier-x6

     

    Then clear the com.apple.appstore directory that is found via the error message in the Console application.

     

    This worked on my end.

    It was deleted as another user said to do. Com.apple.appstoredoes not show up anywhere as there is no error message console application on mine that I can find

    What worked for me - no restart required - after reading all these posts...

     

    1. Disable Virusbarrier X6 (Launch X6, go to preferences > advanced tab, and switch the big slider to 'off'.

     

    2. Launch the Console.app (in Applications > Utilities)

     

    3. Once Console launches, go to View > Clear display (this clears the screen, gets rid of the clutter)

     

    4. Launch the App Store, and try to buy Mountain Lion - you'll get the error message as before.

     

    5. Quit the App Store.

     

    6. Go back to Console - and open the folders of information displayed in the viewer window.

     

    7. In amongst all the gobbledegook text on screen is a parth to the var/folders/ directory. The folder you are looking for will have a name like d3 or zz (it differs on each machine).

     

    8. Once you know the name of the problem folder - go to the Finder, and choose 'Go to Folder' (Cmd-Shif-G)

     

    9. Type in /var/folders in the Go To Folder dialog and click 'Go'

     

    10. In the window that appears, you should see the folder you're looking for, and maybe 1 or 2 others.

     

    11. Drag the problematic folder out on to the desktop (you may need to authenticate to do this) and save this folder in a new folder - 'old var file' or whatever.

     

    12. Select the problematic folder from it's original window, and delete it - Cmd-Delete, and it disappears (but you have the backup copy, just in case. Apparently a new folder will automatically be re-created (by FInder or App Store) - so don't fret too much about removing this folder. And you can always copy your 'backup' back here, if there's a problem.

     

    13. Re-launch the App Store, and try purchasing Mountain Lion. For me - this now worked!

     

    The above worked on a mid-2009 MacBook Pro. I tried a few other suggestions - e.g. re-installing the 10.7.4 combo update but it didn't make a difference. It certainly looks like VirusBarrier X6 is the culprit.

     

    I am currently downloading Mountain Lion - but I did update X6 beforehand to the latest verison, which is supposedly 'Mountain Lion ready'. Once downloaded and installed, I'll go back to VirusBarrier and switch it back on.

     

    Good luck folks!

    As you say, this is the solution. I did the same thing but I also uninstalled the intego software, after that I was able to download mountain Lion.

    Outstanding, many thanks.

     

    Strange that every other item in the App Store (wther free or paid for and whatever file size) except ML is not affected by Virus Barrier X6 but this seems to sort it out.

    THANKS everyone who suggested this - it worked for me! No need to completely uninstall Virus Barrier - as others have said, just temporarily disabling protection under advanced prefs worked for me. It also worked just to delete com.apple.appstore from the problematic folder in /Var/Folders - I originally deleted the whole folder and that caused problems for me (something connected to my fonts library was in there). No restart required.

     

    Now up and running with Mountain Lion (and Intego software) working fine

    To whomever sorted this out.....Big Thanks.

     

    Like others here, disabled VB, used EasyFind to serrch for the folder (i used the string for the comm.apple.appstore) and good as gold.
