Corrupt Mountain Lion File @ App Store?

This is the message I'm repeatedly getting from the app store:

We could not complete your purchase

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


Note the store is otherwise working correctly.

Mac Pro QuadCore (2009), Mac OS X (10.6.7)

If you type in "var" (w/o the quotes) in EasyFider it will give you about 7 results.

Use same criteria (radio-left panel)

Pick the one is Lion>private>var

Then continue to open foders up to C/com.apple.appstore

Make sure that ther is not red circle on the folder (➖)


Most important: Make sure Appstore app is not running when you try to delete the folder. Otherwise will say that the files in the folder are in use.


Good luck.

I too was getting the "The product distribution file could not be verified. It may be damaged or was not signed." message.


As advised by the postings, I did the following:

Quit the App Store app

Moved the "com.apple.appstore/" folder to the Trash

Opened Intego X6

Deauthorized Intego X6 apps

Restarted the computer

Relaunched the App Store app


The error message was gone and I was now able to purchase Mountain Lion


Thanks!
