你只需要在同一個的keyPath內的相應值來添加新條目如下:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<!--
ATTENTION!!! do not edit with an editor which do not handle UTF-8 in a right manner!!
Storing with a wrong editor can crash this file!
Registry definition file for IzPack Installation.
$Id$
-->
<izpack:registry version="5.0"
xmlns:izpack="http://izpack.org/schema/registry"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://izpack.org/schema/registry http://izpack.org/schema/5.0/izpack-registry-5.0.xsd">
<pack name="UninstallStuff">
<!-- Special "pack", if not defined an uninstall key will be generated automatically -->
<!-- The variable $UNINSTALL_NAME can be only used if CheckedHelloPanel will be used
because there the variable will be declared. With that variabel it is possible
to install more as one instances of the product on one machine each with an
unique uninstall key. -->
...
<value name="Publisher"
keypath="SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$APP_NAME $APP_VER"
root="HKLM"
string="MyCompany Software Inc." />
...
</pack>
</izpack:registry>
然後你就可以在大小字段做同樣的。
