Israel, what about 2008 32b?
(In reply to Yaniv Kaul from comment #8) > Israel, what about 2008 32b? windows 2008 32B is derived from other (going through windows 2003 --> XP --> other) os.other.resources.minimum.ram.value = 256 os.other.resources.maximum.ram.value = 65536 # Windows2003(3, OsType.Windows, false), os.windows_2003.derivedFrom.value = windows_xp # Windows2008(4, OsType.Windows, false), os.windows_2008.derivedFrom.value = windows_2003 So it looks like bug in configuration should be 32B according to: https://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx
