I am installing Exchange 2010 on Windows Server 2008 R2 SP1 into an existing Exchange 2003 environment. One of the Prerequisites listed on technet is to install a fix for .NET 3.5 Listed Below. I have downloaded the "Windows6.1-KB982867-v2-x64", however when I run it it says that the Update is not Applicable to this Computer. It does this for many of the Prerequisites listed.
