How To Check If Computer Is Running A 32 Bit or 64 Bit Operating System

 Keywords: OS Platform Version Bit Bitness 32-bit 64-bit

Question:

I am running a winbatch script against the registry on remote servers. Due to registry redirection, it won't work if I'm running on a 32-bit machine and the server is running a 64-bit O/S. So I want to check for that combination, display an error and get out.

I can't seem to find a function that will display the 'bitness' of either my location machine or the remote server.

Answer:

Local machine bitness can be determined using the WinMetrics Function. 
If WinMetrics(-7)|WinMetrics(-2)==3 Then Pause('Windows Bitness','64-bit Platform')
Else Pause('Windows Bitness','32-bit Platform')

Remote machine can be determined using this Registry code: 

intHandle = RegConnect("\\Otis", @REGMACHINE, "")
strPath = 'Hardware\Description\System\CentralProcessor\0'
strValue = RegQueryValue( intHandle, strPath:'[Identifier]')
result = StrIndex( strValue, 'x86', 1, @FWDSCAN)
If result
    Pause('Notice' , 'This is 32 Bit Operating system')
Else
    Pause('Notice' , 'This is 64 Bit Operating system')
EndIf
Or using this WMI Code:

      End If
      Else

      End If
   Next
   vobjItem = 0
   WMIService = 0
   CIMService = 0
   Locator = 0
   Return(varrOSInfo)

#EndFunction

vstrTargetComputer = "OTIS"
varrOSInfo = UDF_CheckRemoteOS(vstrTargetComputer)
Pause('Bitness',  varrOSInfo[0,4])
Exit
