如何区分WIX中的常规安装和升级？ [英] How do I distinguish between a normal install and an upgrade in WIX?

问题描述

我有一些自定义操作，只想在升级方案中执行。

I have some custom actions that I only want to execute in an upgrade scenario.

我正在尝试设置一些属性，例如 MYPROPERTY ...当我通过标准安装进入时，可以对其进行设置，并且该XML的示例如下...

I am trying to set some properties, for example "MYPROPERTY"... When I come in via a standard install, I can set them, and an example of that XML is as follows...

<Custom Action="SetMyPropertyToOn" After="exampleActionRuuningBeforeThisOne"> (ENABLEMYPROPERTY_CB) AND (NOT ENABLEMYPROPERTY_CB="0") AND (NOT ENABLEMYPROPERTY) AND (NOT Installed)</Custom>

它在常规安装中运行...我也希望它在升级方案中运行。

It runs in a normal install... I would also like it to run in an upgrade scenario.

推荐答案

我在所有设置中都使用了它：

I use this in all my setups:

    <SetProperty After="FindRelatedProducts" Id="FirstInstall" Value="true">
        NOT Installed AND NOT WIX_UPGRADE_DETECTED AND NOT WIX_DOWNGRADE_DETECTED
    </SetProperty>
    <SetProperty After="SetFirstInstall" Id="Upgrading" Value="true">
        WIX_UPGRADE_DETECTED AND NOT (REMOVE="ALL")
    </SetProperty>
    <SetProperty After="RemoveExistingProducts" Id="RemovingForUpgrade" Sequence="execute" Value="true">
        (REMOVE="ALL") AND UPGRADINGPRODUCTCODE
    </SetProperty>
    <SetProperty After="SetUpgrading" Id="Uninstalling" Value="true">
        Installed AND (REMOVE="ALL") AND NOT (WIX_UPGRADE_DETECTED OR UPGRADINGPRODUCTCODE)
    </SetProperty>
    <SetProperty After="SetUninstalling" Id="Maintenance" Value="true">
        Installed AND NOT Upgrading AND NOT Uninstalling AND NOT UPGRADINGPRODUCTCODE
    </SetProperty>

然后您可以安排自定义操作仅在升级时运行：

You can then schedule your custom action to only run on upgrades:

<Custom Action="NameOfCustomAction" Before="InstallFinalize"><![CDATA[Upgrading= "true"]]></Custom>
