kix 3.63 does not support @producttype. Give this code snippet a try, it should work for 3.63
Code:
$_ProductType = ReadValue("HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ProductOptions","ProductType")
SELECT
CASE @INWIN = 1 AND $_ProductType = "WinNT" AND @DOS = 5.1
$OSName = "Windows XP"
CASE @INWIN = 1 AND $_ProductType <> "WinNT" AND @DOS=5.0
$OSName = "Win2k Server"
CASE @INWIN = 1 AND $_ProductType = "WinNT" AND @DOS=5.0
$OSName = "Win2k Professional"
CASE @INWIN = 1 AND $_ProductType = "ServerNT"
$OSName = "WinNT Server"
CASE @INWIN = 1 AND $_ProductType = "WinNT"
$OSName = "WinNT Workstation"
CASE @INWIN = 2 AND @DOS = "4.10"
$OSName = "Win98"
CASE @INWIN = 2 AND @DOS = "4.0"
$OSName = "Win95"
CASE 1
$OSName = "Unknown operating system"
ENDSELECT
