It is not working with WINXP !

Loginscript:
start /W %0\..\wkix32.exe %0\..\script1.KIX

script1.kix:
WriteValue ("HKLM\Software\Microsoft\Windows\CurrentVersion\Run", "PostScript", "\\seafs2\netlogon\WKiX32.exe /i \\seafs2\netlogon\script2.kix", "REG_SZ")
exit 0

This works if I run script1 from the CMD line.

Does %0\..\ work with WINXP ?
