HiWelcome to Kixtart.to 
I would go with copying the required files over to the win9x boxes. Easy to implement using the batch file before the Kix script "kicks" in.
Here's a sample batch from Btran:
REM LOGON.BAT
REM =========
@Echo Off
CLS
ECHO Verifying / Updating Script Software Installation, Please Wait...
IF "%OS%" == "Windows_NT" GOTO WinNT
c:\windows\command\XCOPY %0\..\KIX32.EXE %WINDIR%\SYSTEM32\ /D /H /I /R /V > NUL
c:\windows\command\XCOPY %0\..\KX16.DLL %WINDIR%\SYSTEM32\ /D /H /I /R /V > NUL
c:\windows\command\XCOPY %0\..\KX32.DLL %WINDIR%\SYSTEM32\ /D /H /I /R /V > NUL
c:\windows\command\XCOPY %0\..\KX95.DLL %WINDIR%\SYSTEM32\ /D /H /I /R /V > NUL
IF EXIST c:\kix32.EXE DEL c:\kix32.EXE
IF EXIST c:\KX16.DLL DEL c:\KX16.DLL
IF EXIST c:\KX32.DLL DEL c:\KX32.DLL
IF EXIST c:\KX95.DLL DEL c:\KX95.DLL
GOTO RunScript
:WinNT
XCOPY %0\..\KIX32.EXE %WINDIR%\SYSTEM32\ /D /H /I /R /V > NUL
IF EXIST %WINDIR%\SYSTEM32\KX16.DLL DEL /F %WINDIR%\SYSTEM32\KX16.DLL
IF EXIST %WINDIR%\SYSTEM32\KX32.DLL DEL /F %WINDIR%\SYSTEM32\KX32.DLL
IF EXIST %WINDIR%\SYSTEM32\KX95.DLL DEL /F %WINDIR%\SYSTEM32\KX95.DLL
IF EXIST c:\kix32.EXE DEL /F c:\kix32.EXE
IF EXIST c:\KX16.DLL DEL /F c:\KX16.DLL
IF EXIST c:\KX32.DLL DEL /F c:\KX32.DLL
IF EXIST c:\KX95.DLL DEL /F c:\KX95.DLL
GOTO RunScript
:RunScript
ECHO Loading Logon Script, Please Wait...
%WINDIR%\SYSTEM32\KIX32.EXE %1 %0\..\logon.KIX
:End
