3.7.2 update App Store error (20) and manual download error.

I purchased 3.7 from App Store. App Store prompts to update to 3.7.2 but when I start the update I get errror "We could not complete your request. There was an error in the App Store. Please try again later. (20)"
I've tried several times over the past week with the same result.
Today I manually downloaded the admin update. But when I try to run it I get error "The version of Remote Desktop installed on this Mac must be updated through the Mac App Store."
Grrr. How can I resolve this?
Mavericks 10.9.2

I have the same problem, I can't update mine, error 20.
You can try uninstalling ARD and then installing all again, this process will install the whole ARD updated.
You need to be sure you have the serial number (I think there is a serial for this one if you are in a company environment)

Software Update, App Store, Terminal, iCal and other Apple Apps will not open.

Hi,
I've exhausted all my search methods and still haven't fixed this issue. I have been disconnected from the internet for about 5 months up until now while continually using my MacBook Pro (early 2011) daily for work. Problems arose about a month and a half ago when I noticed the terminal would not open. I trashed the corresponding plist files as recommended by other websites and trouble tickets. Still no avail, the affected programs all seem to be original software that came with Mavericks. When I try to open any of them (Software Update..., App Store, Terminal, iCal, iTunes Store) nothing happens. The dock makes a space for the icon and then before anything even bounces it quickly closes the space again. I've tried opening the contents of the applications and running the root program directly.

HT1365 How can I get my iPhone 4 to update my updates from my app store of it keeps telling me error 3150 or it tell me to refresh the page after updates and the updates are still there asking me to update them again

How can I get my iPhone 4 to update my updates from my app store of it keeps telling me error 3150 or it tell me to refresh the page after updates and the updates are still there asking me to update them again?

Make sure iTunes on the computer is logged into the account on the phone.
Plug the iPhone in.
In the popup window warning about wiping your phone, hit cancel.
In the left pane of iTunes, the phone icon should be there.
Right click on it, select transfer purchases.
Note: this will only transfer music bought from iTunes. Not mp3's from amazon or ripped from CD's.

Installing the appropriate combo update may help...
If you are running v10..7 Lion, install the OS X Lion Update 10.7.4 (Client Combo)
For 10.6 Snow Leopard > Mac OS X 10.6.8 Update Combo
Then restart your Mac. Try the App Store.
If that doesn't help, try the following..
Quit the App Store if it's open.
Open the Finder. From the Finder menu bar top of your screen click Go > Go to Folder
Type this exactly as you see it here:
/Library/Preferences/SystemConfiguration
Click Go
Move the NetworkInterfaces.plist file from the SystemConfiguration folder to the Trash.
Relaunch the App Store and try downloading Mountain Lion.
You may also need to disable anti virus software and turn off the Firewall in System Preferences > Security (or Security & Privacy) > Firewall

Hi I am having problems downloading and updating apps on my iPad and iPhone. The message cycles between waiting and loading then I get an error message saying unable to download app. Eventually,after many attempts it works.

Hi Guys - for a few days I have been having problems downloading and updating apps on my iPad and iPhone. The message cycles between waiting and downloading then eventually says unable to download app. Sometimes after many attempts it wil eventually work. I tested it on an old iPhone 3G and got the same problem so it is not an iOS 5 issue. My WI-FI connection is working fine. I was wondering if this is an App Store problem? Anyone else in the UK having this problem?

Hi John
iTunes Support wasn't of any use to me.
I have also been having another problem - with BBC iPlayer and other video streaming not working due to insufficient bandwidth, despite my overall download speed being consistently around 50Gb. This is also affecting AppleTV downloads
I am using Virgin Media as my ISP, and was wondering whether you do as well. This might be the common thread.

1. You did not get an error message telling you that your iPhoto library was getting full. You got a message telling you that your HD was getting full, right?
OS X needs about 10 gigs of hard drive space for normal OS operations - things like virtual memory, temporary files and so on.
Without this space your Mac will slow down as the OS hunts for space on the disk, files will be fragmented, also slowing things down, apps will crash and the risk of data corruption - that is damage to your files, photos, music - increases exponentially.
Your first priority is to make more space on that HD. Nothing else can be done until you do.
Purchase an external HD and move your Photos and Music to it. Both iPhoto and iTunes can run perfectly well with the Library on an external disk.
Your Library has been damaged from being run on an overfull disk.
How much free space on it now?

Is anybody else still not able to use the App Store? I can't download nor update any apps. I have an IPhone 5 device not currently updated to iOS 7 as my partner also has an iPhone 5 running iOS 7 and it seems to have some issues at the moment.

Downloading from the App Store the message "There was an error in the app store. Try again later (4)'. Then 'unexpected error'.

Downloading from the App Store the message "There was an error in the app store. Try again later (4)'. Then 'unexpected error'.
I've been getting this message now for the last couple of days. I can download other apps on my phone with the same apple ID but have now experienced this on my Mac firstly when downloading Yosemite immediately after being asked for my ID password, and then having tested with a couple of other apps, so it's not related to the download.
I'm using OS X 10.9.5 on a Mac Book Air.
I've shut down on a number of occasions and tried again
App Store is version 1.3 (201.7)

Back up all data before proceeding.
Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
Right-click or control-click the line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and test. If there's no change, restore the item you deleted from a backup, overwriting the one that may have been created in its place. Otherwise, you may need to recreate some of your settings in the Network preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

Problem now resolved as I upgraded to Snow Leopard 10.6. Seems App Store doesn't like anything previous to 10.6.

I am unable to use Iboost app, when i try to use it, I get an error "iBoost App is damaged" and reinstall from app store. I get the same error even after installing a fresh copy. Need help to resovle this issue.

“iBoostUp.app” is damaged and can’t be opened. Delete “iBoostUp.app” and download it again from the App Store.
Because of the above error, i am not able to use iboostup application. I have even tried to reinstall from app store, but the issue still continues.
Need help.

Perhaps the damaged file is an auxiliary file outside the app bundle and stored elsewhere on your Mac. Try deleting the app and all it files with an app for that purpose. Afree one is AppCleaner;

From the App Store meny bar click Store > Check for Unfinished Downloads
And check your Applications folder for the app.
Apple's policy > All Sales Are Final > iTUNES STORE - TERMS AND CONDITIONS
Note... it would help to tell us which Mac OS X you have installed when you post for help.
