设置环境变量需要在 64 位上重新启动 [英] Setting environment variables requires reboot on 64-bit

问题描述

我正在使用需要设置系统 PATH 环境变量的 Wix 3.5 安装程序.

I am working on an installer using Wix 3.5 that needs to set the system PATH environment variable.

这就是我设置环境变量的方式:

This is how I am setting the environment variable:

<Directory Id="DirectoryName">
    <Component Id="ComponentID" Guid="{BE20AF67-5943-4AF4-BE66-226E2D4B844F}">
        <Environment Id="EnvironmentID" Name="PATH" Action="set" Value="the path" Part="last" Separator=";" System="yes" />
    </Component>
</Directory>

这似乎适用于 32 位系统，无需重新启动即可识别更改.但是，当我在 64 位 Windows 7 上尝试时，需要重新启动.

This seems to be working on 32-bit systems without requiring a reboot for the changes to be recognized. However, when I try it on 64-bit Windows 7 a reboot is required.

这是 64 位系统上的已知问题吗?

Is this a known issue on 64-bit systems?

也许最好的方法是安排重新启动以覆盖所有基地.

Maybe the best approach would be to schedule a reboot to cover all bases.

谢谢，艾伦

推荐答案

在ServerFault上查看这个问题:如何在不重启的情况下添加 Windows 环境变量?

Check this question on ServerFault: How do you add a Windows environment variable without rebooting?

因此，要将更改传播到环境变量列表，您可以编写一个广播 WM_SETTINGCHANGE 消息，如知识库文章 如何传播系统的环境变量.

So to propagate the change to the list of environment variables, you can write a small program which broadcasts WM_SETTINGCHANGE message as described in KB article How to propagate environment variables to the system.
