Unable to download Mountain Lion OS X

It has me agree to the Terms of Conditions but then says that "This copy of the Install OS X Mountain Lion application can't be verified. It may have been corrupted or tampered with during downloading. Delete this copy of the application, and go to the Purchases page of the Mac App Store to download a new copy." So I go to the app store to retrieve another, and it wants me to buy another one. I don't know what to do, and if it doesn't work I at least want my $20 back HELP!

This has worked for some.
- Sign out of the App Store (in the Store menu)
- Quit the App Store
- In Finder - Go>Go to folder... (or Apple-shift-G)
- Paste in the following "~/Library/Caches/ "
- It will take you to a folder. Delete com.apple.appstore
- Launch the App Store. Sign in and then reclick the Mountain Lion buy.
There is a contact option.

HT4854 Unable to download Mountain Lion because it takes too long....

So far am unable to download Mountain Lion because it's taking so long that my computer goes to sleep then it stops downloading and I have to start all over. Says it takes 9 hours to download. This makes it almost impossible to get the product downloaded. I'm very frustrated and would like to either be able to get it done or get my money back.
Any suggestions? Thanks.

You need to go to Energy Preferences and set computer to
never sleep until you finish your download. Then you can
re-enable it.
BTW, since it takes that much time to download, when the
download completes and the install dialog comes up, cancel
the install and save the installer app to a safe place (USP memory
stick, external drive, etc.) so you don't need to download again
in the future.
After you have save it, then you can run the installer by just
double clicking the app in Applications.

Unable to download Mountain Lion after purchase in App store.

After purchasing Mountain Lion in App store, I have been unable to successfully download a copy.
It was not interrupted, it just stops.
Every attempt (including the first) fails at 142 MB, with the meaningless "unable to download" error. In the console log I find this:
7/31/13 2:32:56.894 PM storeagent: ISStoreURLOperation: Expected bytes (4437341116) did not match actual (142374555)! Setting error. (See 9215068)
indicating the error. The file was expected to be 4.4 GB (yes), but does not match actual 142 MB...?
I have found references to this error, but no real fix. I have tried every "fix" suggested; Safe boot, guest user login, deleting temp files, hidden files, app store files, debug mode in app store, repairing permissions, changing ethernet ports, changing DNS (loved that one), and others.
I finally erased the hard drive with zeroes, re-installed 10.7, software updated to 10.7.5 and immediately attempted download - it still fails.
I also have no virus software or little snitch, or anything else that would prevent downloads. I have been able to download free and purchased software from the app store (xcode, pages, ibooks author) - that are more than 142MB.
So this is not an ISP, modem, or some other thing preventing me from downloading using the app store. It is a problem *only* with downloading Mountain Lion.
This seems like an Apple problem. Anybody have a real fix?

Are you quite sure? Check your model identifier. If you have the first model released, then it cannot run anything past Lion. Be sure you meet ALL the requirements.
Upgrading to Mavericks
You can upgrade to Mavericks from Lion or directly from Snow Leopard. Mavericks can be downloaded from the Mac App Store for FREE.
Upgrading to Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8 or Lion installed. Download Mavericks from the App Store. Sign in using your Apple ID. Mavericks is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

I am unable to Download Mountain Lion for my Mac Pro.

This really *****. Now I know why I can't download Mountain Lion!!!! I have an 8 core Mac Pro at 3ghz
Hardware Overview:
Model Name:          Mac Pro
Model Identifier:          MacPro2,1
Processor Name:          Quad-Core Intel Xeon
Processor Speed:          3 GHz
Number of Processors:          2
Total Number of Cores:          8
L2 Cache (per Processor):          8 MB
Memory:          16 GB
Bus Speed:          1.33 GHz
Boot ROM Version:          MP21.007F.B06
SMC Version (system):          1.15f3
Serial Number (system):          157191HTUPZ
Hardware UUID:          00000000-0000-1000-8000-0019E3F8CB92
And It is too slow to run Mountain Lion. I doubt it. This would not be the case if Apple Supported the Cores parallelism as they are suposed to do. I know this computer is faster than my MacBookPro; How about it Apple, Why not write software to support all my 8 cores and you won;t have to force me to stop using the new Apple System Software. Why can't we users be the ones to determine if our machines run too slow under Mountain Lion? I can't afford a new Mac Pro; you surely now how to hurt a User/Developer.
Thanks for Nothing, Apple!

Unable to download Mountain Lion from the App store

Hi, when I try to download Mountain Lion from the app store I get the message, " The product distribution file could not be verified ... " Obviously I'm doing something really stupid. Advice welcome!
Thanks

A belated thanks for your help. I'd never have solved it otherwise. Maybe Apple could change the automatic reply that I got initially ("The product distribution file could not be verified ....") othewise they risk loosing customers.
Thanks again.

Download error. I'm unable to download mountain lion.

I'm trying to download OS X mountain lion, but the download does not start.
It says that an error occurred. How do I see what error is this?
Thanks a lot.

Thanks a lot Carolyn for the tips, but i didn't manage to get it working through reinstallation of the 10.7.4 combo.
Deb from iTunes Store customer support pointed me to this beauitful article,
https://discussions.apple.com/message/16063398#16063398
I didn't have to install any package, just delete the corrupted file and it works brilliantly after that.

Unable to download mountain lion

could anyone help me as im unable to redeem my software from the app store

It's a two email system. One email has a locked pdf that you need to open with an app such as Preview. It will ask for a password to unlock the pdf. The second email has the pdf password to unlock the file. In the unlocked pdf you will find the redemption code that you need to use with the Mac App Store (MAS) app, not the iTunes app.
Open the MAS app, be sure that you are signed into your account (Store menu), go to the Featured pane. Use the Redeem link in the Quick Links.

MY COMPUTER WILL NOT DOWNLOAD MOUNTAIN LION. 2006 INTEL BASE COMPUTER. MY UNDERSTANDING I CAN STILL DOWNLOAD LION. SITE SAID UNABLE DOWNLOAD IN USA. ADVISE

Unable to download mountain lion. Talking to a apple rep I understand I can download lion. 2006 intel mac desk top (snow leopard). It may not be worth the effort. The plan was to download mountain lion. (Unable to download lion. Not available in the USA.) Any advise would be welcome

Likewise, I compute w/Snow Leopard and play with the last two cats. http://www.macintouch.com/reviews/mountainlion/ covers it well (also apropos for Lion):
It's all about making your Mac and your iPhone and iPad work better together. If you haven't embraced iOS, Apple's touch-based iPhone/iPad operating system, there are some nice enhancements for the Mac itself but little that is groundbreaking.

Problem downloading Mountain Lion from App Store

I am unable to download Mountain Lion onto my iMac from the App Store. I have no problem downloading other software - including updates to Final Cut Pro X and several other programs. However, if I try to download Mountain Lion, it starts and then hangs at 142mb. Since yesterday.
The iMac is 3.4 ghz Intel Core i7, with 8GB of ram, with a SSD system drive. It is currently running 0S X 10.7.5. I have restarted several times, and trashed the preferences and cache for the App Store. I also tried creating an alternate user account on the computer and downloading from the new user - it still hangs at 142mb.
I have already purchased Mountain Lion for my MacBook Pro, and that worked great. The App store recognizes that it is a purchased app - but i am unable to download past 142mb. My internet connection is solid, and I have restarted my modem - not sure what else i can do.

I would first try this:
Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
If you continue to have a problem it may just be any issue with Apple's servers or those of your ISP.

TS2565 why cant i download mountain lion

I am unable to download Mountain Lion onto my Laptop

This is related to your other post https://discussions.apple.com/message/21305789#21305789 where you ask about turning off virus scan before downloading Mac OS X...the answer there applies here, you must turn off anti-virus programs before downloading and installing an operating system.

Still unable to download M. Lion, always get this message "Could not complete your purchase, Unable to verify file distribution. It may be damaged or unsigned." !!!

Still unable to download Mountain Lion, always get this message "Could not complete your purchase, Unable to verify file distribution. It may be damaged or unsigned." !!! Do you have an idea about what's going on ?

Try starting up in Safe Mode..http://support.apple.com/kb/HT1455
Try the App store again.
