Like me if you also forgot to install the MSDN documentation while installing Visual Studio 2010 then don’t worry, it can be installed afterwards.

Step 1: Open Help Library Manager

Launch Visual Studio 2010 then click on Help » Manage Help Settings

It will bring up the Select Location dialog box. You can change the documentation path here, if you want to. But the default path should be ok. Click on Ok button to continue to next dialog.

Step 2: Install From Disk

In this dialog box click on Install content from disk link. Then locate the locate the HelpContentSetup.msha manifest file under the CDROM » ProductDocumentation folder and click Open.

Step 3: Select Contents To Install

In this dialog box choose what help contents you want to install by clicking on the Add link in the Action column. Click on the Update button to start installing.

When the installation is finished click on Finish button to close the dialog box.

Step 4: Choosing Preferred Help Location

At this point the MSDN documentation are installed on your system, but the Visual Studio is using the online help as the main source. To use the local help contents, follow Step 1 to open the Help Library Manager. Click on Settings, then click on the I want to use local help option button and click Ok.

Hope it helps.
