在WiX中，如何测试安装的版本是否至少是特定版本？

Question

我正在建一个WiX丛。我需要链接一个可执行包(实际上是阿斯康 Platform 6 SP1)。检测条件是存在某个注册表项，并且包含大于某个最低要求版本的版本号。如果不满足这些条件，则不满足先决条件，需要下载和安装EXE文件包。

我编写的片段如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<?include $(sys.CURRENTDIR)\Config.wxi?>

<!-- Define a prerequisite for ASCOM Platform 6 SP1 -->

<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"
     xmlns:util="http://schemas.microsoft.com/wix/UtilExtension">
    <Fragment>
        <util:RegistrySearch Id="FindAscom6Installed"
                             Variable="AscomPlatform6Installed"
                             Root="HKLM"
                             Key="SOFTWARE\ASCOM\Platform"
                             Value="Platform Build"
                             Result="exists"
                             Win64="$(var.Win64)"
                             />
        <util:RegistrySearch Id="FindAscom6Build"
                             Variable="AscomPlatformBuild"
                             Root="HKLM"
                             Key="SOFTWARE\ASCOM\Platform"
                             Value="Platform Build"
                             Result="value"
                             Win64="$(var.Win64)"
                             />
        <PackageGroup Id="AscomPlatform6Sp1">
            <!-- If necessary, install ASCOM Platform version 6, do not uninstall
                 it during driver uninstall. -->

            <!-- DetectCondition="AscomPlatformInstalled AND AscomPlatformBuild >= 6.0.10028.2207" -->
            <ExePackage
               SourceFile="ASCOMPlatform6SP1.exe"
               DetectCondition="AscomPlatform6Installed AND AscomPlatformBuild >= 6.0.10028.2207"
               DownloadUrl="http://download.ascom-standards.org/ASCOMPlatform6SP1.exe"
               PerMachine="yes"
               Permanent="yes"
               Vital="yes" />
        </PackageGroup>
    </Fragment>
</Wix>

这将编译OK，但是当安装程序运行时，它会失败。下面是日志输出：

我怀疑问题可能是，因为键不存在，那么AscomPlatform6Build是null，WiX不喜欢它。

如何正确构造此检测条件？

Answer 1

您应该能够根据第一个条件向第二个RegistrySearch添加一个条件。如果还将基值赋值给AscomPlatformBuild，则不会将其报告为null。

<Variable Name="AscomPlatformBuild" Type="numeric" Value="1.0.0" />
...
<util:RegistrySearch Id="FindAscom6Build"
                     Variable="AscomPlatformBuild"
                     Root="HKLM"
                     Key="SOFTWARE\ASCOM\Platform"
                     Value="Platform Build"
                     Result="value"
                     Win64="$(var.Win64)"
                     Condition="AscomPlatform6Installed" />

ExePackage可以单独使用。

Answer 2

面临着同样的问题。通过在条件为 v6.0.10028.2207的版本常数之前添加.i.e v来解决这个问题

<ExePackage
               SourceFile="ASCOMPlatform6SP1.exe"
               DetectCondition="AscomPlatform6Installed AND AscomPlatformBuild >= v6.0.10028.2207"
               DownloadUrl="http://download.ascom-standards.org/ASCOMPlatform6SP1.exe"
               PerMachine="yes"
               Permanent="yes"
               Vital="yes" />
