I'm running Server 2008 SP2 x64 fully patched. The installation for Exchange 2010 is requiring a hotfix that I have not been able to obtain yet. I need the following: http://support.microsoft.com/kb/977592

Fehz, In the same Kb article, left side top, you'll see a link to request a download.... After providing the email address etc, you'll be delivered a link to your email address to download the same hotfix. Incase there are issues with download or so...I would recommand calling MS support to obtain it. Regards, Pushkal MishrA
