I am trying to get information on the version of Windows installed from WMI. Most fields work. I can get the operating system "Name" as well as the "Version", both are fields of the Win32_OperatingSystem object I have.

But another field "OSArchitecture" generates an exception ("Not found").

    strScope = "\\" + strServer + "\root\CIMV2"
    searcher = New ManagementObjectSearcher(strScope, "SELECT * FROM Win32_OperatingSystem")

    For Each mo In searcher.Get

        strOSName = mo("Name")
        strOSVersion = mo("Version")
        strOSArchitecture = mo("Architecture")
        strStatus = mo("Status")
        strLastBoot = mo("LastBootUpTime")

    Next

The documentation says that the field ought to exist and is a String:

Any ideas?

Ignore the for each loop, I don't think it has anything to do with the field missing. The documentation says that the field ought to exist and is a String:
