I and trying to install W2k8_64 using WinPE. I installed WAIK on a W2k8 SP2 system and built WinPE. After booting WinPE I net use to the W2K8_64 bit install directory and run setup.exe. However setup.exe is throwing an error: The version of setup.exe is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need a x86 (32bit) or x64 (64-bit) version of the program, and then contact the software publisher. I built the WInPE environment on a W2k8 SP2 64bit machine. Any insight is appreciated on why this isn't working.
