Problems installing SharePoint 2010 Software Prerequisites

When attempting to install the software prerequisites for SharePoint 2010 on Windows Server 2008 R2, on several occasions, I have encountered errors during the installation which prevented all of the software prerequisites from being installed in a single installation operation.

Interestingly enough, each time the software prerequisite installation failed, it always seemed to fail on the installation of the .Net Framework 3.5 SP1 Hotfix.  (Hotfix for Microsoft Windows (KB976462)).

Fortunately, you can manually download the hotfix from here: http://code.msdn.microsoft.com/KB976462

In some instances, simply installing this hotfix and re-running the software prerequisites installer seems to be sufficient.  In other instances, if this does not work, the other remedy is to simply re-start the machine and then resume the software prerequisite installation.
