问题描述
是否可以将WIX中的环境变量转换为属性?
Is there a way to get an environment variable in WIX into a property?
我正在尝试通过以下方式获取USERPROFILE:
I'm trying to get the USERPROFILE with:
Property Id="UserFolder" Value="$(env.USERPROFILE)\EdwardsApp\MyFolder"
但这只会拾取安装安装程序的构建计算机的USERPROFILE.
But this only picks up the USERPROFILE of the build machine, where the installer is built.
我希望它使用正在安装应用程序的计算机的USERPROFILE.
I want it to use the USERPROFILE of the machine where the app is being installed.
推荐答案
您可以在安装过程中使用环境变量，但这需要使用自定义操作.您将需要使用UserFolder属性. > Type 51 Custom Action ，而不是在构建过程中设置属性. [％ENVVARNAME]格式用于使用环境变量，但是环境变量的名称区分大小写.
You can make use of Environment variables during installation but this requires using a custom action. You will need to set the UserFolder property with a Type 51 Custom Action as opposed to setting the property during the build. The [%ENVVARNAME] format is used to make use of an environment variable, but the name of the environment variable is case-sensitive.
设置属性的自定义操作的WiX示例:

<CustomAction Id="SetUserFolder" Property="UserFolder" Value="[%USERPROFILE]EdwardsApp\MyFolder" />
