在Visual Studio安装项目中从自定义操作设置应用程序文件夹

Question

My Visual Studio 2008 Setup Project must choose the install directory automatically based on a configuration file. I'm using a C# class derived from Installer for the custom action. I read the config file in my Install() method.

How do I change the installer's Application Folder from within this custom action?

Answer 1

The installation folder path is stored in TARGETDIR property.

Installer class actions cannot set Windows Installer properties, so you cannot use your current custom action to dynamically change the installation path.

Only the following custom action types can set installer properties:

• win32 DLL which receives the installation handle
• VBScript and Java Script
• WiX toolset custom action

If you use one of them, you can set the TARGETDIR property to any path you need.
