"The product distribution file could not be verified. It may be damaged or was not signed." Why is that?

Mountain Lion will not download to my iMac, "The product distribution file could not be verified. It may be damaged or was not signed."
I have this problem also. I was able to download Mountain Lion to my daughter's Mac Mini without any trouble. However, I can't download this to my MacBook Pro. I have read other sites that suggest VirusBarrier is the problem and recommend turning it off in VirusBarrier>Preferences>Advanced. I have tried this and it still doesn't work, although some report that it has worked for them.

This is happening when I try to download ibooks. It just doesn't work?
Try this...
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 downloaing Mountain Lion.
Might also need to disable anti virus software and turn off the Firewall in System Preferences > Security & Privacy > Firewall. -

I paid for the Mountain Lion, was downloading perfect. When almost 1 gb of downloading was left then this error occured "The product distribution file could not be verified. It may be damaged or was not signed." and stopped downloading and now every time i try to download it this error occurs
What should i do now, i paid for it and couldn't even download it now.You'll need to re-try the download.
If you have a flaky network connection, or if you're behind a proxy server, there can be issues.
The App Store knows you paid so you won't have a problem trying to re-download, but you will have to re-download. -
HT201364 The product distribution file could not be verified. It may be damaged or was not signed.
what does this mean ?
The product distribution file could not be verified. It may be damaged or was not signed.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 keep getting the message "The product distribution file could not be verified. It may be damaged or was not signed." Does anyone know what I can do to correct this so I can download OSX?
I have a MacBook Pro with all the necessary requirements.Here are a few things to try:
Restart your Modem and Router.
Reset iTunes Store Cache (iTunes Preferences, Advanced tabl)
Delete the App Store plists (close App Store first):
~/Library/Preferences/com.apple.appstore.plist
~/Library/Preferences/com.apple.storeagent.plist
To get to these,iIf you still have your user Library hidden, hold down the Option key and select Library from the Go menu in Finder. Otherwise, just go into your home folder, then Library, and then Preferences. -
Can someone help out. I'm getting this message when i try to download. The product distribution file could not be verified. It may be damaged or was not signed.
See this link from another similar question. It may need patience to resolve. I think Thomas Reed's suggestion is best place to start.

I do not speak English, however I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own.

Whenever I try to update my iPhoto program I get this error message "The product distribution file could not be verified. It may be damaged or was not signed."
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, or by a peripheral device.
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, 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.
