The software could not be varified.it may have been corrupted or tempered during downloading

i have already purchase mac os x lion .it was now saved in appstore on my mac.but i could not able to install it.

The file may have been corrupted when you downloaded it, go to Applications and find the installer for Lion. Trash it. Restart App Store, it should show up for Install. Re-download it. and try and re-install it.
Make sure you use the same apple ID account and pass word as before.

Cannot install Mac OS X lion because when installing I recieved the following message:The software could not be verified. It may have been corrupted or tampered with during downloading" What can I do

I have not been able to install Max OS X Lion because in the process the following message was displayed:
"THE SOFTWARE COULD NOT BE VERIFIED. IT MAY HAVE BEEN CORRUPTED OR TAMPERED WITH DURING DOWNLOADING"
How can I solve this?
Note: I trashed the download and tried re-downloading but this effort was unsuccessful.

Since writing my original post I decided to send the following message to Mac App Store Customer Support:
"I have had to download this file from the app store at least ten (10) times. I try to install the file but I keep getting the message "The software could not be verified. It may have been corrupted or tampered with during downloading."
I then delete the same file and try another attempt at a different time of day. Most recently following Apple Support's advice I contacted my ISP to clear the file cache but they could only clear my browser cache. I have deleted my com.apple.appstore. folder which contains app store cache, also com.apple.appstore.plist and tried again to no avail. I have wasted hours doing all this and I now want my money back please. You can keep this software update until you release it on disk like Snow Leopard which installed like a dream. I'm very disappointed with Apple that they expect the purchaser to do all the work trying to diagnose their software installation issue. Nice idea but poorly executed has been my experience."
I received this message which has confirmed my refund request:
Julia here from the iTunes Store. I understand that you received an error message and have been unable to install OS X Lion. I know how eager you must be to have this resolved, and I will be happy to help in any way that I can.
Please accept my sincere apologies for the frustration this download has caused. Since you were unable to enjoy this purchase, I have gone ahead and issued a refund. In five to seven business days, a credit of £20.99 should be posted to the credit card that appears on the receipt for that purchase.
If you have any other questions or concerns regarding this issue, please reply so I can assist you further. Thank you for being an iTunes Store customer.
Sincerely,
Julia

Perhaps I'll wait for a disk to become available or see if a download to a pen drive at an Apple store is possible.

Latest update returns error " None of the selected updates could be installed. The update could not be expanded, and may have been corrupted during downloading. The update will be downloaded and checked again the next time that Software Update runs."

Which latest update? Details get answers. Rather than using SU, DL and install from http://support.apple.com/downloads/.

I can't install OS x lion, The software could not be verified. It may have been corrupted or tampered with during downloading.

I can't intall the OS lion. is show me this message, The software could not be verified. It may have been corrupted or tampered with during downloading.?

I encountered the same error "…can't be verified…" error on my 2010 MBP too. Tried six times and finally I could get it installed. Here's what I did:
Went to "Users & Groups" in System Preferences, checked that the Apple ID specified for the current user is the same Apple ID I used in the download purchase of ML from the App Store.
Rebooted in Safe Mode.
Went to Disk Utility -> Repair Disk Permissions
Downloaded ML at midnight (and the download was significantly faster!)
Rebooted in Normal Mode.
Ran the ML Installer.

You have a defective download and need to re-download the installer.

The first thing to attempt is restarting in Safe Mode, this will clear some caches. It's possible one or more has become corrupt. Once it has started navigate to 10.6.8 Update Combo and download and install per the directions. After it has installed if you still have difficulty re-starting, go to System Preferences - Startup Disk and make sure the internal HD is highlighted and click restart again and restart again in Safe Mode. Finally restart normally.
BTW I have asked the moderator to remove the serial number of your machine for your own security. Please DO NOT post private information such as email addresses, serial numbers etc.. to a public forum.

When trying to download the New Lion Software from the App Store I get this. The software could not be verified. It may have been corrupted or tampered with during downloading. I am signed in as the administrator - what do I do?? Thanks

The couple of times I got a message like that, repairing permissions on the boot volume fixed the problem.

All Appstore and Mac updates Fail saying "...could not be verified or may have become corrupt"

Recently my Mac started to become glitchy so I decided to wipe the hard drive and reinstall my OSX Mountain Lion. After doing so almost all of my updates fail showing this msg "...could not be verified or may have become corrupt". Not to mention downloading updates take ridiculously long. I have 80mbps down and small updates say they could take up to 2 days. I wanted to try upgrading to the the newest OS however that also has the error msg…not to mention a 4 days estimated download!
any help with this would be greatly appreciated!
and yes I did set my date and time to automatic.

I'm trying to update my Mac book pro to 11.0 and I get an error message at end of attempt. The message says 'the update java os 10.6 update 15 can't be saved. Update could not be verified . May have been corrupted during downloading. '. Any ideas?

Question typed in subject space. Sorry!

Hi there Amy,
You may want to take a look at the article titled "Troubleshooting Mac OS X installation and software updates (Mac OS X v10.6 and earlier)"
There is a specific section that includes this information:
Software Updates for Mac OS X and Apple applications for Mac OS X are often available in different ways:
Software Update preferences
Standalone installer from Apple Downloads.
Try getting the software from a different source, or download it again.
Hope that helps,

Lion install errors out with msg that software could not be verified, it may be corrupted or tampered with during download. Re-downloads produced the same error.

Tried a number of downloads of Lion and none of them would get by the error in the subject line. Help pls?

I was in your same situation with 14 downloads and 14 attempts.
You have to make sure that your Mac is booting into 64 bit mode. You can make sure of this by going into System Preferences and scrolling down to 'Software' and making sure that you are booding with 64 bit Kexts.
If not, restart while holding the 6 and 4 keys down until you see the spinning gear wheel and try installng again.
BUT, what I also did was to go into Applications, click on the Lion installer, Get Info, and give yourself custom priviliges to Read And Write.
I did this simultaneously, and I don't know what function did it, but it worked for me, with no further downloads of the installer.
Good luck!

Lion Install Failing: software could not be verified

So I download Lion, start the installer and I get the following error message pop-up:
The software could not be verified. It may have been corrupted or tampered with during downloading.
It took me nearly 7 hours to download this thing so downloading again is not an option. So is there any way I can fix this?
Here is the error that's being logged in the console when I run the installer:
7/21/11 10:56:51 AM          Install Mac OS X Lion[9980]          Error loading /Applications/Install Mac OS X Lion.app/Contents/PlugIns/IACoreStorage.IABundle/Contents/MacOS/IACoreStorage: dlopen(/Applications/Install Mac OS X Lion.app/Contents/PlugIns/IACoreStorage.IABundle/Contents/MacOS/IACoreStorage, 265): Library not loaded: /usr/lib/libcsfde.dylib
Referenced from: /Applications/Install Mac OS X Lion.app/Contents/PlugIns/IACoreStorage.IABundle/Contents/MacOS/IACoreStorage
Reason: image not found
Of course, /usr/lib/libcsfde.dylib doesn't exist anywhere on my 10.6.8 MacOS installation.
Anyone else run into this problem?

Thanks for the reply. In another posting, the md5 checksum of a fully downloaded file should be:
     b5d3753c62bfb69866e94dca9336a44a
This is for the installESD.dmg file inside the installer (right-click on "Install Mac Os X Lion" which will be in your /Applications folder after the download (but before the install - will get deleted after the install is complete); select 'Show Package Contents" from the menu; go into "Contents"; go into "SharedSupport"; you'll see the InstallESD.dmg disk image here).
To get the checksum, from Terminal, navigate to the directory (see paragraph above) and run:
     md5 InstallESD.dmg
So I wasted my entire morning trying to figure out why this wasn't working. How is it that Apple can't inform you that the download didn't complete successfully?!!? Major $%^& up.

After downloading , i have problem on installing an error "the software could not be verified. it may have been corrupted or tampered during download" can reinstall
