If all you are wanting to do is make sure that the current version of kix is installed on the local client.....you might want to do this from the same batch file that launches your logon script and use the xcopy command.code:
@Echo OffCLS
ECHO Verifying / Updating Script Software Installation, Please Wait...
IF "%OS%" == "Windows_NT" GOTO WinNT
%windir%\command\XCOPY %0\..\KIX32.EXE %WINDIR%\SYSTEM\ /D /H /I /R /V > NUL
%windir%\command\XCOPY %0\..\KX16.DLL %WINDIR%\SYSTEM\ /D /H /I /R /V > NUL
%windir%\command\XCOPY %0\..\KX32.DLL %WINDIR%\SYSTEM\ /D /H /I /R /V > NUL
%windir%\command\XCOPY %0\..\KX95.DLL %WINDIR%\SYSTEM\ /D /H /I /R /V > NUL
ECHO Loading Logon Script, Please Wait...
%windir%\system\kix32.exe %0\..\logon.kix
GOTO End
:WinNT
XCOPY %0\..\KIX32.EXE %WINDIR%\SYSTEM32\ /D /H /I /R /V > NUL
ECHO Loading Logon Script, Please Wait...
%WINDIR%\SYSTEM32\KIX32.EXE %0\..\logon.KIX
GOTO end
:End
