Go to App Store and download. If it doesn't help, press Shift key when your Mac starts up, go to App Store > Purchases and download Mountain Lion

What do I do if the Mac App Store won't except my code for the OS X Mountain Lion code?

My mac app store won't load and when click it nothing happens happens

my mac app store won't load and when you click it nothing happens...it was okay for the past months but now i don;t know why it won't open...please help...

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. 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 software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up 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 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, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Mac App Store Won't Work After Upgrading HDD

I'm on a Macbook Pro 2011. I had Mavricks. I downgraded my OS because I had hardware that wouldn't work with Mavricks. I also upgraded my HDD. I tried to open Mac App store but it won't open. The icon will appear on my dock and the App Store title bar appears, but all the opions in the menu are greyed out and not clickable.

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.

Mac App Store won't allow re-downloading of deleted apps

I am experiencing very glitchy behaviour with the Mac App Store. The store can't tell when individual apps are deleted, and therefore won't allow re-download. This has been going on for a while - when I click on the Purchases tab all Apps are still listed as Installed and the button is greyed out - I can't click to re-download. At the same time, an app that I previously did download and later removed called Cobook won't delete from the computer - after a few minutes to an hour it will re-appear in my Applications folder.
I have done a clean re-install of Mountain Lion trying to fix this problem, however the same problem exists even after a re-install - Apps that had been deleted prior to the clean install are still greyed out in the Purchases tab, and can't be re-downloaded. The only way that Apps can be re-installed is to use Time Machine backup. I am concerned that this means that updates also aren't working, since the App Store doesn't seem to know what Apps are on my computer and which ones aren't.
Yes I am using the correct Apple ID assocaited with the purchases. My purchase history shows up just fine in the Purchases tab, its just that they are stuck showing that they are currently installed, even the ones that aren't.
Mountain Lion 10.8.2, 21.5" iMac (mid-2011).

The problem is possibly worse than I expected. Since the clean re-install, now any App purchased and downloaded via App Store won't appear in the Purchases tab. So in other words, although the download seems to work correctly, and the app works, the App Store seems to lose all track of it. Which is a problem for paid apps.

     *shouted at the Mac (sorry for that)
     *booted in Safe Mode - tried the same things there
     *unmounted Boot camp
     *deleted all cache, property and cookie files
     *unpacked the 10.6.6 combo package and used the commerce framework from there, and the App Store too
     *pulled my hair
     *and so on...
Nothing helped!
PLEASE tell me how can I start the Mac App Store again!!?
Thank you!!

Since you have Lion installed, use Lion Recovery

Mac App Store Won't Sign Me Into My Apple Account

Today, I was going to download and install an app from the Mac App Store. So, I opened the App Store, found the app, and clicked download and then install. Of course, it popped up the box to sign into my Apple account. I typed in my e-mail and password and click "sign in". It began its little turning-circle "loading" icon on the little box (not the beach ball). But nothing ever happened. After 15 minutes, I forced quit App Store and tried again. Again, same thing. I did this a total of three times. So, I decided not to touch it and just let it run its course. Well, it's been at least four hours now, and no change. Still "signing in", but nothing's happening. Has anyone else had this problem? Because I can't find anything anywhere about this on the discussions site. Help! Please!

Go to Settings > Store and sign-out. Sign-in again using your Apple ID. Of course this won't help if the apps were purchased using your friend's ID.

Jedi Knight II from Mac App Store won't start on 10.8. Suggestions?

About a week ago, I purchased Jedi Knight II from the Mac App Store despite already having a copy purchased years ago when it first became available for the Mac. Naturally, I figured that with a high percentage of people using Lion and Mountain Lion, if there were a problem with this game, it would probable not remain on the app store. I downloaded it and attempted to launch. The screen where you choose if you want to play Windowed or Full Screen popped up just fine and I chose Full Screen. I waited a while and nothing happened. I attempted to choose something from the related menues that popped up and all I got was the spinning beach ball. When I opened the "Force Quit Applications" screen, it said the app was not responding. This is what I have gotten consistantly every time I have tried it. I figured that before I go to apple to request a refund, I would ask if anyone has had this issue and if you were able to resolve it.
Thanks,
Marc G

Create a new user test account on your machine. See if you can play it from there without difficulty.

Mac App Store won't Update Purchase...

Hello
I have a Macbook
It is running 10.6.8
I purchased Angry Birds through the Mac Appstore (not itunes.. the Mac App store..) a while ago.
I noticed last night there was an update available (on the Dock, a little red 1 in the App Store logo)
I click on the App store logo and click on Updates
I see the update that is available
I click on that and get this error message
"You Have Updated Available for Other Accounts..
To update this application, sign in to the account you used to purchase it."
However.. I have NO other accounts..
I have been in touch with Apple Support and they cannot help me and said I should contact Roivo support.. however this seems more an AppStore issue than an App issue
I have run the command to make sure I have no 3rd party apps installed (I don't)
There is no pirated or illegal apps on this computer
I have uninstalled and reinstalled the Angry Birds app and still the same error.
Previous updates to this particilar app were fine..
Thoughts?

Just per chance, you could try this;
Finding a pirated app
All MAS apps have a MAS receipt in their app bundle. Check any app acquired from the MAS. Right click on the app's icon in your Apps folder and choose Show package contents. In the Contents folder is a _MASReceipt folder and in that folder is the coded MAS receipt. It has the Apple ID of the MAS account that bought/acquired the app from the MAS. It is that receipt that the MAS uses to alert you that an app has an update. There would not be a notice of an update with someone else's Apple ID showing in the MAS on your Mac, if there was not an app with a receipt from this person's account somewhere on your Mac.
Download the free app FindAnyFile (FAF);
http://apps.tempel.org/FindAnyFile/
This app is easier to use and seems to be more powerful than Spotlight. Open FAF and in the box type _MASReceipt and press Find. It should come up with a list of every app on the Mac with a MAS receipt. Compare the apps with receipts in FAF's list with your purchased apps list in the Mac App Store. The odd app out should be the pirated app.

OS 10.6.8, mac app store crashes at launch, and safari crashes if I open a tab

Ok, so i have had these problems for a while now, but i never bothered to try and fix them till a couple weeks ago because they are becoming really frustrating. both of them have been occuring before i updated to 10.6.8.
The first problem is on Safari, whenever i open a tab safari unexpectedly quits. I have tried reseting safari completely, but that didn't fix it either.
My mac app store also unexpectedly quits whenever i try to open it, I have tried the option suggested in other solutions where you find all the different files and move them to the trash, that didn't work. So then i tried deleting it all together and reinstalling it with the latest combo package. And that didn't work either.
Today I got the system update for 10.2.8, i thought maybe that would fix it, but i still experience both of these problems and i don't know what to do.

In that case:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

HT1338 Mac app store won't let me update iPhoto and iMovie.

I'm trying to update iPhoto & iMovie, just got a new mac and when I go into the Mac App Store and click update on iPhoto and iMovie it says: "To update this application, sign in to the account you used to purchase it." .....both came pre-installed on my mac and I only have one apple ID, I don't have another one to sign into... please help?

You should be able to go the Mac App Store, login with your Apple ID that you have set up and registered, and then since you just bought the iMac New you should find those two Apps to click on listed in the "Purchases" List that is associated with your Apple ID account. You may or may not need to, for Free, redownload those two Apps from the Purchases List to trigger allowing Free Updates. I'm not sure, not having done this that way.
Hope this helps

Mac App Store won't accept my password

Ok, well I sent tech support an email about this yesterday and never heard back, so I guess I'll give this a go...
The main problem is I can't access my account in the Mac app store. Everytime I enter my password its says "unkown error occured".
I did change my password yesterday before this problem arose, I don't know if that has anything to do with it or not, but the new password works in iTunes...

Forgot to mention - iCloud login in System Preferences works fine with the new password, further confirmatin that the password has definitely been changed.

Mac App Store won't work

I just upgraded my iMac to OSX 10.6.7 from 10.6.6 and Mac App Store will not open. Its icon is dimmed in the Applications Folder and I get a application crash and report window whenever I try to open it. For what it's worth, it wasn't on my machine when I had 10.6.6.

You might want to purchase an external hard drive to use as a back up. Time machine is great for backing up everything on your Mac and you can get an external hard drive for less than $100.
If you are not sure which may be corrupted you can actually trash all of the Preferences in your Users, Library, Preferences Folder and restart. Be sure to save all important settings first as you will have to reset them in some instances (such as your Mail.app settings). Or, you can down load system maintenance utilities which can look for corrupt preferences. TinkerTool System is excellent and is shareware. It's worth the small price. Also, Applejack which is free. I use both.
If you reinstall from your install disk be sure to use the Archive and Install setting. Everything on your Mac will be saved.
Before you go through the reinstall though, I suggest you download, install and use Applejack first. It's very user friendly and may solve your problems. Read about it first before using it. It's a trip to watch if you haven't seen Terminal.app in action.
You can download Applejack and TinkerTool System from macupdate.com.
Again, back up all your stuff!

Mac App Store won't let me install something I already bought.

I just bought a game on the Mac App Store and it was in the middle of downloading. I turned the monitor off and when I turned it back on it wasn't downloading anymore. I still don't have it in my Applications folder so I tried to install it again but it said 'We could not complete your purchase. The product distribution file could not be verified. It may be damaged or was not signed.' What do I do?

Restart the computer
Search using spotlight to make sure its not there
Look at launchpad
Anything?
