I have changed the syntax, thought I was correct? But still does not work? Can you see why?

;Check users desktop for CIS install

if ingroup("nw2_CISinstall")

if exist ("c:\CISinst.txt")
quit 1
endif

if @inwin = 1
if not exist ("c:\CISinst.txt")
copy "S:\CIS\CISInst.txt" "C:\"
copy "S:\CIS\Desktop\*.*" "C:\Documents and Settings\All Users\Desktop" /s
copy "S:\CIS\Applic\*.*" "C:\Program Files" /s
endif
endif

if @inwin = 2
if not exist ("c:\CIS_Inst.txt")
copy "S:\CIS\CISInst.txt" "C:\"
copy "S:\CIS\Desktop\*.*" "C:\Windows\Desktop" /s
copy "S:\CIS\Applic\*.*" "C:\Program Files" /s
endif
endif


endif
