i made a little bat file "tempdir.cmd"

@echo off
TITLE Create temp directory
cd /d c:
md temp
for %%i in (C D E F G H I J) do if exist %%i:\CDROM_IP.5 set CD=%%i
%systemroot%\regedit.exe /s %CD%:\i386\svcpack\temp.reg
exit

that i put into svcpack folder and call from svcpack.inf [setupHotfixesToRun] section.

;Windows 2000 Professional
;!!!!!! delete svcpack.in_ in the I386 directory !!!!!!

[Version] 
Signature="$Windows NT$" 
MajorVersion=5 
MinorVersion=0 
BuildNumber=2195  

[SetupData]
CatalogSubDir="\i386\SVCPACK"

[SetupHotfixesToRun]
HFSLIP1.CMD
HFSLIP2.CMD
HFSLIPIE.CMD

;temp folder
tempdir.cmd

the problem is that the corresponding reg file "temp.reg"

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Environment]
"TEMP"="c:\\temp"
"TMP"="c:\\temp"

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment]
"TEMP"="c:\\temp"
"TMP"="c:\\temp"

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Session Manager\Environment]
"TEMP"="c:\\temp"
"TMP"="c:\\temp"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]
"TEMP"="c:\\temp"
"TMP"="c:\\temp"

is nicely imported into registry, but the folder "temp" is not created! why?? running from command prompt, the folder is created without a problem (it so simpel command ... ) but running the same from svcpakc.inf nothing happens can someone put me in right way??

Make A SFX rar file and place the cmd in there.

yeah the answer was as simpel as was the question: the code:

@echo off
TITLE Create temp directory
cd /d c:
md temp

didn't create the directory

but the code:

@echo off
TITLE Create temp directory
cd /d c:
md c:\temp

made the temp directory

maybe there should be command extensions enabled or somethign else to use the simplest syntax (ie md temp). i dunno :/ in command shell both make a directory.
