使用C#.net升级MSI文件 [英] Upgrading msi file using C#.net

问题描述

大家好
我试图在互联网上找到一些信息，但似乎找不到关于此的任何教程.

基本上，当有人安装我的应用程序时，我会检查他们何时运行该应用程序，以查看是否有可用的更新.如果有可用更新，它将下载并运行新的MSI文件. (全部完成).

我遇到的问题是，当您运行新的MSI文件时，我无法获取它来实际升级程序.由于更改了版本号，因此我在安装文件中将版本号从3.0更改为4.0，然后选择是"以更新ProductCode.我将RemovePreviousVersions设置为True，并将DetectNewerInstalledVersion设置为True.

我是否遗漏了任何东西，或者是否有人知道描述该操作方法的文章?

Hi All
I have tried to find some information on the internet but can''t seem to find any tutorials on this.

Basically when someone install my application I will have it check when they run the application to see if there is a update available. If there is a update available it will download and run the new MSI file. (This is all done).

The problem I am having is when you run the new MSI file, I can not get it to actually upgrade the program. I have changed the Version number from 3.0 to 4.0 in the setup file and then select yes to update the ProductCode since I changed the version number. I have RemovePreviousVersions set at True and DetectNewerInstalledVersion to True.

Am I missing anything or does someone know of a article that describes how to do this?

推荐答案

UpgradeCode必须始终相同，而ProductCode必须在新版本中进行更改.
我在Visual Studio 2010中使用了它，并且效果很好.

UpgradeCode must always be identical, where ProductCode must change on new builds.
I use this under Visual Studio 2010, and it work just fine.
