For installing the K1000 agent on different systems as Win XP, Win 7-32 and Win 7-64, I wrote a little VB script which can be modified easily. It is especially designed to run KACE agent deployment on remote locations with a local share for KACE software distribution.

' Install KACE Agent per policy on Win XP, Win 7-64, Win 7-32
On Error resume next ' error handling, just cancel script

programfiles = ""
osversion= ""
osarchitecture = ""
fname= ""
cmdstring= ""

Set WshShell = WScript.CreateObject("Wscript.Shell") ' get environment strings
programfiles = WshShell.ExpandEvironmentStrings("%programfiles%")

Set ObjWMI = getobj("winmgmts:\\.\root\cimv2") ' get os name and version
Set ObjOsList = ObjWMI.instancesOf(("win32_operatingsystem",48)

For each ObjOsDetail in ObjOsList ' extract os name and version
	osversion = ObjDetail.Caption
	If osversion = "Windows 7 Professional " Then ' catch WIN XP, os architecture not supported - mind space at end of comp string
		osarchitecture = ObjDetail.OsArchitecture 
		If osachitecture = "64-Bit" Then ' different path for x86 programs
			programfiles = WshShell.ExpandEvironmentStrings("%programfiles(x86)%")
		End If
	End If
Next

fname = programfiles & "\Dell\KACE" ' string installation path
Dim Fso
Set Fso = CreateObject("Scripting.FileSystemObject")

If Fso.FolderExists(fname) = false then ' not installed
	cmdstring = "msiexec.exe /qn /l*v %windir%\temp\ampmsi.log /i <\\path_to_your_share>\ampagent-5.5.30275-x86.msi host=<name_of_your_k1000-system>
	WshShell.Run cmdstring
End If
