如何在运行时(安装时)从 wix 源代码中获取 MSI 文件所在的路径 [英] How to get the path of Where MSI file is located from wix source code at run time(Installation time)

问题描述

我想在执行安装时从 WIX 源代码中找到 MSI 的路径.我尝试使用 $(sys.SOURCEFILEPATH) 返回我需要的内容(C:\temp\myProj\sample.msi)).但是，当我将 MSI 文件复制到不同的文件夹 (D:\temp\sample.msi) 并尝试安装时，我得到的路径与以前相同(C:\temp\myproj\sample.msi).

I want to Locate path of MSI from WIX Source code when we perform installation. I tried using $(sys.SOURCEFILEPATH) which returns what I need (C:\temp\myProj\sample.msi)). But when I copy MSI file to a different folder (D:\temp\sample.msi) and tried to install I am getting the same path as previous(C:\temp\myproj\sample.msi).

提前感谢您的回答

推荐答案

Windows Installer 将 OriginalDatabase 属性设置为用于启动安装的安装数据库的路径.

The Windows Installer sets the OriginalDatabase property to the path of the installation database used to launch the installation.
