Wix IIS版本检查启动条件不起作用 [英] Wix IIS Version check launch condition not working

问题描述

您好，我正在尝试添加启动条件以检查安装的 IIS 版本是否大于 7，否则应显示合规性消息.

Hi I am trying to add launch condition to check IIS Version installed is greater than 7 if not it should display compliance message.

 <PropertyRef Id="IISMAJORVERSION"/>
   <Condition Message="Install requires IIS 7 or higher">
    <![CDATA[IISMAJORVERSION AND (IISMAJORVERSION >= #7)]>
    </Condition>

也试过 IISMAJORVERSION >= "#7" 和 IISMAJORVERSION >= "#7" 但是它没有在没有安装 IIs 的机器上显示条件消息.请帮忙.

Also tried IISMAJORVERSION >= "#7" and IISMAJORVERSION >= "#7" but it is not showing condition message on the machines which doesn't have IIs installed. Please help.

推荐答案

由于 IISMAJORVERSION 是一个字符串，我们不能执行大于或小于.因此我将我的条件修改为以下.

As IISMAJORVERSION is a string we cannot perform greater than or lesser than. Hence I modified my condition to below.

<PropertyRef Id="IISMAJORVERSION"/>
 <Condition Message="Installer requires IIS 6 or 7 or higher versions installed on the machine.">
<![CDATA[(IISMAJORVERSION <> "") AND (IISMAJORVERSION <> "#1") AND (IISMAJORVERSION <> "#2") AND (IISMAJORVERSION <> "#3") AND (IISMAJORVERSION <> "#4") AND (IISMAJORVERSION <> "#5")]]>
</Condition>
