Question

我一直在玩Wix，用自动生成的安装程序制作一个小应用程序，用三个版本测试可升级性，1.0,1.1和2.0。

1.1意味着能够从1.0升级，而不允许用户在1.1已经存在的情况下安装1.1。

        <Upgrade Id="MY_UPGRADECODE_GUID">
            <UpgradeVersion Minimum="1.0.0"
                                            IncludeMinimum="yes"
                                            Maximum="1.0.0"
                                            IncludeMaximum="yes"
                                            Property="OLDERVERSIONBEINGUPGRADED" />
            <UpgradeVersion Minimum="1.1.0"
                                            IncludeMinimum="yes"
                                     OnlyDetect="yes"
                                     Property="NEWERVERSIONDETECTED" />
        </Upgrade>

        <Condition Message="A later version of [ProductName] is already installed. Setup will now exit.">
            NOT (NEWERVERSIONDETECTED OR Installed)
        </Condition>

问题＃1：1.1无法卸载，因为在卸载过程中设置并检查了条件。

2.0意味着能够从1.1升级，而不是从1.0升级（'太旧'。）它不应该能够自己安装。

    <Upgrade Id="MY_UPGRADECODE_GUID">
        <UpgradeVersion Minimum="1.1.0"
        IncludeMinimum="yes"
        Maximum="1.1.0"
        IncludeMaximum="yes"
        Property="OLDERVERSIONBEINGUPGRADED" />
    </Upgrade>

    <Upgrade Id="MY_UPGRADECODE_GUID">
        <UpgradeVersion Minimum="2.0.0"
        OnlyDetect="yes"
        Property="NEWERVERSIONDETECTED" />
    </Upgrade>

    <Upgrade Id="MY_UPGRADECODE_GUID">
        <UpgradeVersion Minimum="1.0.0"
        IncludeMinimum="yes"
        Maximum="1.0.0"
        IncludeMaximum="yes"
        Property="TOOOLDVERSIONDETECTED" />
    </Upgrade>  

    <Condition Message="A later version of [ProductName] is already installed. Setup will now exit.">
        NOT NEWERVERSIONDETECTED OR Installed
    </Condition>

    <Condition Message="A version of [ProductName] that is already installed is too old to be upgraded. Setup will now exit.">
        NOT TOOOLDVERSIONDETECTED
    </Condition>

问题2：如果我尝试从1.1升级，我点击了修改后的版本条件。（错误：已安装更高版本的主应用程序 1.1 。安装程序现在将退出。）问题3：安装程序允许我在自己的顶部安装2.0。

我的升级代码和条件在我的MSI中出现这些问题我做错了什么？

好的，我发现有一个技巧可以用来检测卸载。

我的1.1版WXS改为：

        <Condition Message="A later version of [ProductName] is already installed. Setup will now exit.">
            NOT NEWERVERSIONDETECTED OR REMOVE ~= "ALL"
        </Condition>

和版本2.0：

        <Condition Message="A later version of [ProductName] is already installed. Setup will now exit.">
            NOT NEWERVERSIONDETECTED OR REMOVE ~= "ALL"
        </Condition>

        <Condition Message="A version of [ProductName] that is already installed is too old to be upgraded. Setup will now exit.">
            OLDERVERSIONBEINGUPGRADED OR (NOT Installed AND NOT TOOOLDVERSIONDETECTED) OR REMOVE ~= "ALL"
        </Condition>

所以我的LaunchConditions永远不会在Uninstall上启动，并且会正确检测哪个版本正在升级。

我假设当你提到你的app的给定版本时，比如“app 1.1”，你总是在谈论相同的可安装图像。与多个不相同的可安装映像（例如，具有不同的包代码）相反，这恰好碰巧共享产品版本号。

如果是这种情况，那么当已安装app 1.1时，您无需执行任何操作来明确阻止用户安装app 1.1。安装程序服务将识别已安装app 1.1，并且不允许您再次安装它。它将出现在维护模式中。它认为您想要添加或删除功能，或者可能要卸载该产品。
