XCode 4.5 downloading documentation I have installed XCode 4.5. During the installation there was an error about downloading the documentation. I did not pay much attention, but I think the error was same as that mentioned in: 
this question.

I tried the solution as mentioned in the post, but there is no file named as: "com.apple.adc.documentation.AppleOSX10_8.CoreReference.docset" as stated in the answer.

The main problem I have with the documentation is that it is incomplete. While some of the pages are displayed properly, the other pages are blank. 

How do I repair the documentation? I am ready to re-download the documentation. I do NOT want to download the entire XCode 4.5 again. Please help!!!

Note: I am using Mountain Lion 10.8.
You can do that directly form Xcode preferences:


Open Xcode
Menu Xcode > Preferences
Go to the tab Download 
Go to the sub-tab Documentation
Select the documentation you want to re-install
Click the - icon below the documentations list for moving it to the trash.
Click install on the desired documentation


Maybe you can skip the step 6 if Xcode shows that the documentation is not installed.
