I recently purchased some software which will only run on the 64bit version of Windows, so I need to do a clean install of the 64bit version of Server 2008. When I ran the Intel Process Utility it told me that my processor was 64bit capable, but when I boot in WinPE (no DVD drive you see) and run the R2 installer I get this error:
This version of setup.exe is not compatible with the version of Windows you're running.
Do I have to enable 64bit mode? If so, how?
This is the offical installer for Windows Server 2008 R2 64bit I'm using from the Microsoft website.
Server: HP Proliant DL380 G4, 6GB RAM, 300GB SCSI
