Exchange Stats via Powershell template

I have installed the Exchange management tools as listed in the prereqs of the Exchange Stats from PS template. I also noticed a Windows Hotfix was listed as being required but for Server 2003. I am on 2008 R2 so do I need to apply this hot fix? The hot fix addresses 64 x OS trying to access a 32x folder or something of that sort. My template is failing but I am not sure if its due to the hotfix or something else.
