OKay think ive worked out now what you mean 
try something like this
Code:
script2:
Gosub Acrobat
GoTo end
:Acrobat
Dim $uninst, $leftpart, $rightpart
;Read Registry key to determine if AR4 is installed
$uninst=ReadValue("KLM\Software....", "UninstallString")
If $uninst<>""
WriteProfileString ("c:\temp\Yes.txt","Yes","Yes","yes")
Call \\server\kix\acrobat7.kix
Else
WriteProfileString ("c:\temp\No.txt","No","No","No")
Call \\server\kix\acrobat7.kix
endif
Return
script3:
If exist ("c:\temp\yes.txt")
Gosub ar4_detected
Endif
If exist ("c:\temp\No.txt")
Gosub MSIparam
Endif
Gosub Install
{code...
}
del
Something like that
