"Unsupported" is shown if the operating system is NOT Windows XP, Windows Vista, or Windows 7. The flavor installed (e.g. Professional vs. Ultimate) does not matter, nor does the Service Pack level. We pull the operating system name from Inv_AeX_AC_Identification. Please check the [OS Name] column for the computers showing "Unsupported" and report back what the values are. If there is a record missing, or if the field is NULL (or blank), you will also see "Unsupported" because we don't know what the OS is.
