Mac App Store will not install Mountain Lion update

I am having an issue where I try to install the 10.8.4 update from the Mac App Store. I click on the button and it says it needs to restart to install. I tell it to restart and install but it does nothing. I get the Mac App store back with it asking me to install the update again. Looking at the infobox I see that I am still on 10.8.3.


Any thoughts on how to fix this?


Thanks

MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)

Sometimes, the App Store version doesn't work correctly. In this case, install OS X 10.8.4 using the Combo version > http://support.apple.com/kb/dl1659


The Combo version is the safest way to update OS X. Also, it allows you to update more than one Mac with one download

Give this a try:


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.


After this is completed download and install 10.8.4 Mountain Lion Update v10.8.4 (Combo).
