Make sure your Mac qualifies for Mountain Lion > Upgrade your Mac to OS X Mountain Lion.
If you have anti virus software installed, disable that before downloading apps.
Turn off the Firewall in System Preferences > Security (or Security & Privacy) > Firewall
Try deleting the cache, cookies, and preference files (plist) associated with the App Store.
Quit the App Store if it's open.
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type this exactly as you see it here:
~/Library/Caches/com.apple.appstore/Cache.db
Click Go
Move the Cache.db file to the Trash.
Now here:
~/Library/Preferences
Click Go
Move these files from the Preferences folder to the Trash.
com.apple.appstore.plist
com.apple.storeagent.pllist
Now here:
~/Library/Cookies
Click Go
Move the com.apple.appstore.plist file from the Cookies folder to the Trash.
Empty the Trash, try the App Store.

File and product distribution could not be verified. it may be damaged or was not signed. ?

I get this as a pop up when I try to purchase and install "Pages" and "Numbers" on my brothers iMac. Thoughts as to what I might be doing wrong?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Product distribution file could not be verified. it may be damaged or was not signed.??

whenever i try downloading anything on the appstore that's what it says.. i don't know what to do... i'm no expert on computer and i can only understand basic instructions. english is not my first language.. can anyone please help me??
all the other similar threads about this that i saw were from 2011 and i did not find them very helpful that's why i am asking this.. please help

Several causes for this problem have been reported. Please take each of the following steps that you haven't already tried. Stop when it's resolved.
Step 1
If possible, test on another network, such as a public hotspot (if the computer is portable) or the hotspot created by a mobile device. A network gateway that blocks some traffic, most likely on a company or university network, could be causing the error.
Step 2
Back up all data.
From the menu bar, select
 ▹ System Preferences... ▹ Network
If the preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advanced button and select the Proxies tab. If any proxy options are selected, make a note of them and then deselect them. You don’t need to change the bypass or FTP settings. Click OK and then Apply. Test. The result may be that you can't connect to any web server. Restore the previous settings if that happens.
Step 3
Rebuild the Spotlight index. If you try to search now from the magnifying-glass icon in the top right corner of the display, there will be an indication that indexing is in progress.
Step 4
Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

I went to Purchases and it worked from there having had the same problem you describe.

I tried downloading the latest OS X Mountain Lion and [after a long time... I have a slow connection] I got an error message ... The product distribution file could not be verified. It may be damaged or was not signed.

Hi folks,
I tried downloading the latest OS X Mountain Lion and [after a long time... I have a slow connection] I got an error message ... We could not complete your purchase The product distribution file could not be verified. It may be damaged or was not signed.
Everytime I retry or continue the download I just keep getting the same error message!!!
What can I do to get my product?

The only thing that worked for me was to boot in safe mode.
Power down. Then press power button and hold 'shift' key until grey screen with progress bar appears... Once booted and logged in just open safari and browse to applestore.
No trouble at all once I did this.
Reminder: create full backup before you upgrade OS
Hope it helps.

Installing the appropriate combo update may help...
If you are running v10..7 Lion, install the OS X Lion Update 10.7.4 (Client Combo)
For 10.6 Snow Leopard > Mac OS X 10.6.8 Update Combo
Then restart your Mac. Try the App Store.
If that doesn't help, try the following..
Quit the App Store if it's open.
Open the Finder. From the Finder menu bar top of your screen click Go > Go to Folder
Type this exactly as you see it here:
/Library/Preferences/SystemConfiguration
Click Go
Move the NetworkInterfaces.plist file from the SystemConfiguration folder to the Trash.
Relaunch the App Store and try downloading Mountain Lion.
You may also need to disable anti virus software and turn off the Firewall in System Preferences > Security (or Security & Privacy) > Firewall
