VS2010 How to install MSDN repeatedly

Try to install VS2010 this year, because there has been a lot of changes in the use of vs2008,vs2010 installation, the most typical is the installation of MSDN, I would like to install MSDN locally (after all, Internet access is not very convenient), Unlike VS2008, there is an obvious MSDN Install button, installed after the VS2010 only to find no MSDN, and do not know how to install, so began to some degree, found nothing but the following answer:

2. dot "Choose online or local Help", then select "I want to use local Help"
3. Click Install content from disk, and then select the Productdocumentation\helpcontentsetup.msha file under the VS2010 installation disc
4. Click "Add" to select the MSDN Library content you want to install, then click OK to start installing the
5. (optional) tap Check for updates online to update the local MSDN Library documentation on-line for the latest content.
6. press F1 in VS2010 to open the Help Library, and the first time you open it will run an additional help Library Agent process, and then call the default browser to open the Help Library. The Help library has been changed to Web mode and has not been indexed.

The answer is good, the problem is not done, miss the correct installation of MSDN set the opportunity, and then want to follow the above do not have the opportunity to install, but also to find some of my situation as a friend of the question, but the answer times all are the above answer, not clear is the answer is the IQ has a problem or the eyes have problems, I don't even know what people are asking. There is also a reliable answer is, miss this opportunity, there is no chance to install again, the answer is not at least seriously look at the other people asked what the problem.

Is there really only one installation opportunity for VS2010 's MSDN? In almost despair, another search engine (that is, the high-profile exit of the company's) to find the answer, this time finally a bit of a look, the general meaning is this: VS2010 MSDN has a special Help document viewer program location generally in the "C:\Program Files\Microsoft helps Viewer\v1.0\" This directory, there is a usage instructions readme_chs.htm, Looked at is to modify the HelpLibManager.exe.config file, the inside of the "<add key=" Firsttimerun "value=" False "/>" modified to "<add key= "Firsttimerun" value= "True"/>", meaning to tell the manager, this is the first time to start the fruit Viewer, the management can automatically set the prompt user MSDN installation of relevant settings, and then refer to the above method basically almost solved.

Another problem is that because I use the VS2010 installation package is a virtual CD-ROM loaded with the ISO image, the Productdocumentation directory is the entire MSDN installation package, if the installation directly specify the library path for this directory, will prompt no modification permissions, The solution is to directly copy the contents of the Productdocumentation directory to your designated library path location, and then install it, after the installation can be packages this directory deleted, save hard disk space, Because this is the MSDN installation package zip file, it is no longer available after loading.

As you can see, VS2010 MSDN can be installed repeatedly, and you can change the installation location of MSDN at any time to adjust the hard disk space.
