Download mountain lion from applestore to replace Mavericks

Since I purchased my iMac, I have evidence of mountain lion on record. It is my understanding I can just go to Apple Store and download Mountain Lion, which would then eradicate the Mavericks that I recently installed and dislike.
Any issues with going that route to get back to good old Mountain Lion OSX?

Apple tech said if I have record of purchase , which I do, that I can go online to Apple store and install mountain lion (again), which would eliminate Mavericks. I thought that sounded like a marvelously easy fix. So, is Apple tech wrong ?
The tech is correct, in as much that if your Mac came with Mountain Lion or earlier installed (which I presume it woud have) then you can reinstall Mountain Lion. What he didn't tell you was that it will wipe all your data and settings. Folow the instructions that Caroline posted above. Hopefully you have or can backup important data.
Mavericks has probably overwritten some data that was once able to be read in Mountain Lion. But they should be still accessable from your backup from prior to you Mavericks install.
Good Luck

How to restore macbook after downloading Mountain Lion from app store

I just downloaded Mountain Lion from the app store. How do I restore my Macbook to it's factory settings without the CD? (Since I downloaded it online without the CD)

Welcome to the Apple Support Communities
If you want to reinstall the original Mac OS X version that came with your computer, you need the Mac OS X DVD that came with the computer.
If you want to reinstall Mountain Lion, the installer creates a recovery partition to reinstall OS X and do some maintenance tasks. You can access to it pressing Command and R keys while your Mac is starting

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.

Can I get a direct download link other than from app store

Try opening the Terminal utility in your system and running the following command to open the system's caches folder:
open $TMPDIR../C
Then locate and remove the folder called "com.apple.appstore" and then try relaunching the App Store and downloading the installer again.

I cannot download mountain lion from the App Store

I am unable to download Mountain Lion from the App Store, I keep getting an error every time I try to purchase the app, I have been trying for a week but no luck.
Can someone please help.
My current opperating system is Lion, which has been updated from Snow Leopard.

Yes, my Imac is a 2010 model, and I have checked the requirements, they are all fine.
The error message is
The product distribution file could not be verified. It may be damaged or was not signed.
do you have any suggestions?
Thank you

I downloaded Mountain Lion from being on Snow Leopard and lost my entire Office 2004 suite, including Entourage which was my main email server. If I download Office 2008, will I retrieve all my lost Entourage email folders?

Other options?

It's not that simple. You didn't lose your Office 2004 suite. Office 2004 won't run in Mountain Lion. You need to update your Office software. You need to purchase either Office 2008 or 2011. Either one can run in Mountain Lion.

I keep getting "hash mismatch" when trying to download Mountain Lion from the App store

I've been trying to download the new Mountain Lion from the App Store & keep getting "hash mismatch" message. I was able to download on my 1 computer, but no luck on the 2nd computer, which is up-to-date on all updates & software. Support even put a fresh copy of the App in my account & I still get that same message. Someone suggested AppCleaner, but how do you delete the OS to re-install the new. Didn't think that was possible. Any suggestions - I've tried quitting & logging out of the App Store & even re-starting (several times)

- Temporarily disable anti virus software if installed.
- Apps such as Little Snitch, Net Nanny, and Hands Off can prevent apps from downloading including Mountain Lion.
How to re download apps from the Mac App Store:
Open the App Store. From the menu bar click Store > Sign In
Click Purchases from the top of the App Store window.
Select Mountain Lion. Then right or control click where you see Installed then click Install.
Make sure and use the same Apple ID used for the original purchase.

Downloading Mountain Lion from The Mac App Store.

I'm currently downloading Mountain Lion for my Imac from the Mac App Store. If I put my computer to sleep, the download stops, can I put my Desktop to sleep or will the download still stop?

Welcome to the Apple Support Communities
You can pause the download as many times as you need. The download will resume when you wake up the iMac

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.

How do you erase and reinstall a hard drive without a disc? I bought this mac book pro under a year ago and am pretty sure i downloaded mountain lion from the app store. Basically Im having startup issues and this is the final step Ive reached

when I start my laptop it loads a third of the way and shuts down automaticallyI've tried to safe boot, repairing discs and clearing RAM but nothing has worked. basically I've come to the final step of having to a erase my hard drive and reinstall mountain lion however Apple support suggest that I install from a disc however I installed mountain lion from the App Store. can anyone help me go about this?

Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
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.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Downloaded Mountain Lion from App Store, but it says by disk is locked and won't let me choose the hard drive for installation

I'm struggling to get Mountain Lion installed on my machine, but what is worse is that it has essentially rendered my computer useless (and of course I need to use it urgently). After downloading and installing from the App Store, I have run into some significant problems.
On install, when prompted to "select the disk where you want to install OS X" the hard drive is greyed out and a message comes up that says "The disk is locked."
So when I back out of the install, I am given the option for Disk Utility, Reinstall OS X (same results as before) or Restore from Backup (not backed up).
On the Disk Utility, I can hit Verify Disk and it names an error and says to hit Repair Disk. The error is an "Invalid Sibling Link. The volume Macintost HD was found corrupt and needs to be repaired." Unfortunately, Repair Disk is greyed out and I can't hit it.
What I want to do is just forget the entire process at this point and scrap the upgrade until I have time to figure out what is going on. Is there a way to abort at this point?
Thanks for any help!

Your welcome!
You should always have and keep an up to date backup.
Sounds like you need something a little stronger than Disk Utility. At this point I have no way of knowing if Disk Warrior can or will help.
Depends..!
If you do format and install, then Yes it will.
If you reinstall OS X, then No it will not.
Problem is that according to the Disk Utility message, I don't think that you will be able to install either 10.6 or 10.8.
Those are very good questions. The only bad questions are the ones you have to ask yourself.
