Copy the SharePoint Foundation.exe (or setup.exe) installation file to a folder on the computer where you are installing SharePoint and doing your development, such as in the following path:

c:\SharePointFiles

Extract the installation files by opening a Command Prompt window, and then typing the following command at the directory location of the folder where you copied the installation files in the previous step.

For SharePoint Foundation 2010:

c:\SharePointFiles\SharePoint /extract:c:\SharePointFiles

For SharePoint Server 2010:

c:\SharePointFiles\OfficeServer /extract:c:\SharePointFiles

Using a text editor such as Notepad, open the installation configuration file, config.xml, located in the following path: c:\SharePointFiles\files\Setup\config.xml

Add this line inside the <configuration> tag:

XML

<Setting Id="AllowWindowsClientInstall" Value="True"/>

Save the configuration file.

Review the complete configuration file. It now looks similar to the following for SharePoint Foundation 2010. The complete configuration file will be longer for SharePoint Server 2010 (and therefore the text below cannot replace the contents of that file), but should use the same setting for the AllowWindowsClientInstall attribute.

XML

<Configuration>
  <Package Id="sts">
    <Setting Id="SETUPTYPE" Value="CLEAN_INSTALL" />
  </Package>
  <DATADIR Value="%CommonProgramFiles%\Microsoft Shared\Web Server
   Extensions\14\Data" />
  <Logging Type="verbose" Path="%temp%" Template="Microsoft Windows
   SharePoint Services 4.0 Setup *.log" />
  <PIDKEY Value="PIDKey Value" />
  <Setting Id="UsingUIInstallMode" Value="1" />
  <Setting Id="SETUP_REBOOT" Value="Never" />
  <Setting Id="AllowWindowsClientInstall" Value="True"/>
</Configuration>
