Re-Installing Mac App...

it seems as though the app was uninstalled on my Mac. Can't figure out how to re-install it?

If it’s in a backup, restore it from there. If not, back the computer up, restart with the Command and R keys held down, and reinstall the OS.

I can't install mac app store on my MBA!!!

I can't install mac app store on my MBA and I have the snow leopard 10.6.8, and I try to do a software update, and Mac App Store never installs. can anyone help me please?

I can't install Mountain Lion because I can't install Mac App Store

I have Snow Leopard, and have purchased a download of Mountain Lion. The instructions say I can't get the download without going to the Mac App Store. I tried, and that seemed to require a download of Yosemite. I downloaded Yosemite, which took an hour, and now can't install it because I get a message saying this computer uses Time Machine for backups. In fact, I don't use Time Machine, so I tried taking it out of applications. However, I still get the same message. I am totally stuck, going around in circles. Is there a way to get the Mac App Store without going through Yosemite? Is there a way to download my purchased update to Mountain Lion without encountering all these extra problems? Thank you for any help.

See OS X- Cannot install on a volume used by Time Machine for backups. You should not have delete the Time Machine application.
If you have 10.6.8 installed then you can open the App Store on your computer. On the right under Quick Links is a link, "Redeem." Click on that. Enter the redemption code you were sent for Mountain Lion. After it is accepted the download will start. If you now click on the Purchases icon in the toolbar, you will find Mountain Lion entered and a progress bar for your download. You should see something similar on the Launchpad item in the Dock, if you have one.
After the Mountain Lion download has successfully completed it will automatically launch. My advice: before you click on the Install button locate the Mountain Lion installer in your Applications folder and put a copy of it in your Downloads folder for safe keeping. Once you have completed the Mountain Lion installation the installer will be deleted automatically. By having your own copy you can make a USB flash drive installer:
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
Use DiskMaker X to put your installer clone onto the USB flash drive. Wait for the process to complete which will take quite some time.

Clean install & Mac App Store (Can't reinstall Apps)

Hello Everyone,
I just did a clean instal of OS X Lion and after signing into the Mac App Store, it is telling me that programs are already installed (which they are not). If I try to update or anything it tellls me these are associated with another account.
"To update this application, sign in to the account you used to purchase it."
How do I get around this?
Regards,
CLM

Just to confirm, you can boot into the Recovery Drive by holding down Command R when restarting.
When you select to reinstall OS X, what happens?
Fix for missing MAS
It's possible #1 will do the trick, but you might need to do the additional steps in Keychain access.
1. Delete the files /var/db/crls/crlcache.db and /var/db/crls/ocspcache.db. These can be found using Finder’s Go >; Go To Folder menu (Cmd + Shift + G). This resets the cache of accepted certificates in the system. It doesn’t remove them, it just forces the system to rebuild the caches upon restart.
2. Open Keychain Access (/Applications/Utilities/Keychain Access). Select Certificates in the Category picker on the left side. In the search bar, type in the word Class. Look through that list, and find any certificates that have a blue + symbol over their icon. These are the ones you need to modify.
Select one that has a blue +, and hit Command + I. Click the disclosure triangle beside the “Trust” list to show the list of permissions. Now, what we need to do is to set this certificate to use the system defaults. However, for some reason, when you select it, it doesn’t save. So what you need to do is this. Under “Trust”, where it says “Secure Sockets Layer (SSL)”, change the dropdown menu to say “No Value Specified”. Then, close the window. It will ask for your administrator permissions. Then, open the info pane for that certificate again. Under “Trust” again, now set the dropdown that says “When using this certificate:” to say “Use System Defaults”. You can then close out of the info pane, and enter your password again. Do this for any of the certificates that have a blue + on their icon. There should only be one or two at most.
(Note: I had to toggle the settings before it would stick)
Restart your system.

Why can't I install Mac app store

Hi I want to install the Mac App Store to have the chance to Install OS X Lion. But eveytime I'm trying to go to the App Store it brings me back to the overall of Mountain Lion OS. Can you help me guys? Thank you!

I think that you have to be running OS X 10.6.8 Snow Leopard (or some version of Snow Leopard at minimum) in order to have the Mac App Store. Your tagline says that you are running 10.5.8 Leopard.

Install Mac App Store apps on more than one computer

Can install apps, downloaded from the Mac App Store, on two different computers? I have downloaded and installed a number of apps on my iMac, now I want to sync my iPod with my MacBook, instead of the iMac, and would like to know if I can install these apps on my MacBook, so that they can then be synced with my iPod again. Please let me know. An help would be appreciated. Thanks.

You did not download any apps from the Mac App Store for your iPod. The Mac App Store only sells apps for the Apple Macintosh computer as the Mac in the store's name implies.
You should be posting this type of question about iOS apps in the iTunes Store forum, as you bought these apps from the iTunes Store's App Store;
https://discussions.apple.com/community/itunes/itunes_store
Yes, the iOS apps on your iMac can be transfered to your MacBook. One quick way is to use your LAN. Drag and drop the apps from the iMac which are located in ~/Music/ITunes/iTunes Media/Mobile Apps onto the iTunes app on your MacBook.

How do I install mac app store?

I have a 2010 iMac I just bought from a friend and with snow leopard 10.6.8 installed. The App Store App is damaged and I can't figure out how to reinstall it. I want to upgrade to Mountain Lion, but I can find no way to do this without purchasing it from the app store.

Delete it and rerun the 10.6.8 combo updater.

Any way to install Mac App Store Lion release to partition?

Not sure if this violates any NDAs or whatever.. was just curious if anybody knows if there is / will be a way (once Lion is released) to install it to a partition.
I'm going to need to test my work software to ensure it is compatible, before I upgrade.
Thanks in advance.

Google making DVDs, thumb drives and SD cards with the Installer. Then you are reading outside the ASCs where other folks having defied their NDAs!

My 10.8.3 update did not install properly citing an 'Unknown Error'. Now, my Mail and Mac App Store aren't working. What went wrong and how do i fix it ?

My 10.8.3 update did not install properly citing an 'Unknown Error'. Now, my Mail and Mac App Store aren't working. What went wrong and how do i fix it ?

I tried this and still have the same problems. If I open Address book or the Mac App Store I get the library rebuild popup and a hang. I created a fresh user and then things are better apart from the printing issue. Its clearly some 3rd party software issue but the crash logs are meningless to me. I used the excellent Etre check app from http://www.etresoft.com/etrecheck so I have a list of what is being loaded and can compare clean and crashed user info but as I cant work out which of the startup items, launch agents, launch daemons etc that are causing the problem.
I have eliminated Dropbox, Mac Keeper and Witness, and it isnt related to my exterrnal LED cinema dispay or my external thunderbolt drives, or any USB devices if thats any help to anyone else. Info from Etrecheck follows -

Adobe Creative Cloud app not displaying already installed apps and can't install new apps Mac OS 10.9

Hi,
I've been using the new Adobe Creative Cloud 2014 for a couple weeks now perfectly fine, until yesterday. I use Photoshop, Illustrator, and After Effects quite extensively. This morning, I opened the Adobe CC app and all but Adobe Acrobat Pro show installed. The other already installed apps have buttons to "install" but clicking this button shows the "Exit Code: 7 - Unable to complete Silent workflow" error in the logs. Ive tried disabling my Sophos antivirus program and restarted several times. The already installed applications themselves seem to function normally, they open and work projects. I've even tried to uninstall one of the already installed programs (Bridge) and it fails to uninstall, saying I need to restart my computer and disengage my anti-virus, which I've done. I've uninstalled and reinstalled the Adobe CC app as well, and have the same result. Help.

So I've completed the solutions listed in the help article with no changes. Here is how it has gone with each solution listed in the article. Also, it is not clear in the article whether these steps are to be done in sequence or may solve the problem individually, but since Solution 1 fails for me, doing them in sequence was impossible.
Solution 1: Mac OS: Run the uninstaller in the Applications/Utilities/Adobe Installers folder to remove the program listed as up-to-date.
This does not work because uninstalling any of these applications does not work. As I stated in the post, the uninstaller for all of my adobe applications (photoshop, bridge, indesign etc) throws the same error each time saying I need to: restart my computer (done) close all applications (done) and disable my antivirus (done, which was fully engaged when I installed the apps originally with no issue) and disable my firewall (done, I don't use one). Not sure what I'm missing on that, plus its a real bummer that I need to reinstall all of my CC apps even if the uninstaller did work because my creative cloud app won't recoginize they've been installed.
Solution 2: Remove the OPM.db file and relogin into the Creative Cloud desktop application using the Adobe ID tied to your subscription.
This did nothing.
Solution 3: Download and install the latest version of Adobe Creative Cloud desktop app from Creative Cloud for desktop.
This did nothing.
Solution 4: See the steps listed in Solution 1 to remove all installed Adobe Creative software. Once all Adobe Creative software has been removed, use the CS Cleaner Tool to ensure a complete removal. You can find details in Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6.
This did not do much because I can't uninstall the software to begin with.
What am I missing?

How do i download the new software onto my computer so then i can install the new itunes? i dont have the mac app thing either and it wont let me do it from the itunes because my server is not working. how do i fix it?

Hey so i have a version of a mac i think it is kinda old, it is the all white one i got it like 4 years ago maybe. I got a new ipod recently and i cannot downloade any music onto it. this is because i tried to download the new itunes which it said i needed and now when i try to install it. It says i need a new software so i try to download that and is says i need the mac app or something. but it says i need the new software to get that. so i went onto itunes and clicked the apple and pressed new software and it goes onto this little thing that says my internet is alright but my server has not been connecting.

First things first: Pull down the Apple Menu and select "about this Mac" and tell us what version of OS X is currently on your computer.

My Mid-2011 Macbook Air becomes extremely hot when installing apps from the Mac App Store and when deleting apps

My Mid-2011 Macbook Air 13-inch (OSX 10.8.1 Mountain Lion) becomes hot to the touch when trying to delete large documents, watching videos after waking it from sleep-mode and when installing applications from the Mac App Store. This has also been happening with OSX Lion before I upgraded it to Mountain Lion.

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico my first language is Spanish. 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. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
What needed to be done the day that you set up the new Mac was go into the Mac App Store (MAS), sign into your iTunes/MAS Apple ID, go to the Purchases pane and Accept the iLife apps that would have been there in a special section. That would have sent you Mac's unique identifier code to Apple's servers and verified that this Mac was eligible for the bundled iLife suite and then registered these apps into your MAS account.
You might try going to ~/Library/Caches/com.apple.appstore/adoption.plist, delete the adption plist, restart the Mac and then go to the Purchaes pane and see if you can Accept the apps into your account.

Tried to open a file I created in Numbers a while ago which I modified on 11/4/13 and got a message that I needed a newer version of Numbers. When I went to the Mac App Store it shows that the new version is already installed. Any suggestions?

Are you launching Pages from an icon in your Dock? Installing the update does not change the Dock icons & it does not remove the older versions. Go to your Applications folder & launch the new Pages from there.

Problem with Resuming and Installing Apps Purchased using Mac App Store

Recently I have been trying to download and install AeroFly FS which I purchased from Mac App Store (17GB) and with my internet connection it take some 4-5 days to download that.
I have 2 problems.
1) Resume download don't work if I happen to reboot my macbook pro for some reason after pausing the download before the reboot. When I reboot and try resuming the download... the resume button changes to install, and the download start afresh, I technically lost all my previous downloaded data.
2) The app was 17GB ( I guess thats the installer), and I had some 25GB left after the download completed. But it gave an error saying while installing that not much disk space. So I moved/deleted many item on my drive and got the disk space to some 37GB Free. But it was still giving the same error of not much disk space.
So, I thought the new avaialable diskspace was not accounted for. So, I rebooted the macbook. And to my agony, I found the roboot wiped out the 17GB installer I managed to download from Mac App Store.
So, far i have wasted almost more than a week trying to download and install this app. Now, I am re-downloading it for the third time.
Any Help will be highly appreciated.
Any Tips on how I can move the installer once it sdownloaded to my external HDD, and where can i find this installer which App store downloads?
Regards,
Sapam

Hi ...
37GB of free space is not enough.
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure there's a minimum of 20% free disk space.

How do I download an app from the Mac App Store but not install it yet?

How do I download an app from the Mac App Store but not install it yet?
Can I simply download it and not install?
What if the App gets updated before I download it?
Why? Well, I am very busy and wish to install at my leisure even though I have purchased the App (required at a specific day in the month in order to appear on my business accounts).
Thanks.

There is a difference in what Kappy stated and what you stated. A major paid upgrade (v2.x to v3.0), yes, costs money, as it would in any other delivery stream. Updates (v3.0 to v3.1) to a a major version are free.
Most apps sold through the Mac App Store (MAS) are the type that use the simple drag & drop installation. Those are downloaded directly to the designated apps folder and installation is done. Large pro-type apps download an installer to your Apps folder. Those you can install at your leisure. The MAS does not have a lot of apps using this type of installation.
Be sure to always backup your MAS purchases, because there is no guarantee that the app will always be available for download in the future and it is your responsibility to archive copies.
