Question

我可能做错了什么？我的Windows Installer AppSearch在Windows 10上为RDP二进制文件获取的版本与Explorer / Properties和wmic报告的不同。

我们的产品需要最近的RDP，因此MSI使用AppSearch检查mstscax.dll的文件版本。奇怪的是它找到了6.3版本，而wmic和Explorer都将版本报告为10.0（在完全更新的Win 10系统上）。

使用wmic：

C:\Users\Alan> wmic datafile where name="C:\\windows\\system32\\mstscax.dll" get manufacturer, name, version
Manufacturer           Name                             Version
Microsoft Corporation  c:\windows\system32\mstscax.dll  10.0.15063.483

在资源管理器中右键单击该文件也会将版本显示为10.0.15063.483

但使用此WiX Appsearch代码失败：

    <Property Id="RDPVERSIONWIN10">
        <DirectorySearch Id="Win10RdpVer" Path="[System64Folder]">
            <FileSearch Name="mstscax.dll" MinVersion="6.4" />
        </DirectorySearch>
    </Property>
    <Condition Message="Appsearch for mstscax.dll failure">
        <![CDATA[Installed OR RDPVERSIONWIN10 ]]>
    </Condition>

条件只有 MinVersion =＆＃34; 6.3＆＃34; 才能成功。有趣/巧合的是，在Windows 7上，最新的RDP版本是6.3

我无法理解这一点......有人可以解释一下吗？

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

为了完整性，这里是我测试的所有（最小）wix代码

使用Orca的Fwiw显示MSI表中的值与WiX代码正确匹配。
