I'm trying to run the following update package: WindowsServer2003.WindowsXP-KB2536276-v2-x64-ENU.exe downloaded from here: http://technet.microsoft.com/en-us/security/bulletin/ms11-043 but when I run it I get the error " is not a valid Win32 application."
I am running it on Windows Server 2003 R2 x64 and made sure I downloaded the correct file for my OS.
I am installing this file manually (along with others) because I do not have access to the MS Updates site as I am in a locked down environment. The company update server is not accessible until this machine is joined to the domain. IT won't join it to the domain until this and other patches are installed... so patches must be downloaded and installed manually.
The Affected OS list doesn't mention Windows Server 2003 R2. Windows 2003 != Windows 2003 R2
