blocks|key|205707|text|很难说是什么导致了这一切。如何安装不删除以前版本的MSI？我建议运行不使用详细日志记录的安装。我会像这样从命令行运行它：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|205708|msiexec+/i+"project.msi"+/l*v+"c:\install.log"|code-block|syntax|javascript|205709|/l告诉msiexec+(这是安装程序服务)创建日志，*告诉它记录所有内容，v告诉它使用详细模式。|205710|运行它，并查看日志文件，它将告诉您哪些失败以及原因。你也可以把日志文件发到这里，我打赌我们可以一起找到一些东西。|205711|ADDITIONL问题:日志文件使看起来像是安装程序认为没有什么可做的。当您声明更新文件版本时，您正在更新什么？如何部署包含的文件？是否将它们作为“主要输出”包含在安装项目中，还是直接包括程序集？您是否确定了依赖项并自动包含它们，还是包含了项目输出？|offset|length|style|BOLD|205712|有关需要更改哪些内容以自动升级MSI的.，请参阅本文|205713|entityMap^0|0|0|0|0|0|H|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|W|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|X|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|Y|8|@$M|Z|N|10|O|P]]|9|@]|A|$]]|$1|Q|3|R|5|6|7|11|8|@]|9|@]|A|$]]|$1|S|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|T|$]]

It's hard to say what may be causing this. How are you installing the MSI that does not remove the previous version? I would recommend running the install that is not working with verbose logging. I would run it from the command line like this:

<pre><code>msiexec /i "project.msi" /l*v "c:\install.log"
</code></pre>

/l tells msiexec (which is the installer service) to create a log, * tells it to log everything, and v tells it to use verbose mode.

Run that, and take a look at the log file and it should tell you what is failing and why. You can post that log file here too and I bet we can find something together.

ADDITIONL QUESTIONS: The log file makes it look like the installer thinks there is nothing to do. When you state you update the file version, what are you updating? How do you have the files included to be deployed? Do you have them included as "primary outputs" in the setup project, or are you including the assemblies directly? Do you have it determining the dependencies and automatically including them, or did you include a project output?

UPDATE See this post for a description of what needs to change to automatically upgrade MSI's. <a href="https://stackoverflow.com/questions/511789/how-do-i-persuade-a-vs2005-msi-to-upgrade/513169#513169">Question 511789</a>

blocks|key|77230|text|您是否试图在应用程序运行时进行更新？如果是这样，那是不可能的。您需要想一种更好的方法，比如使用一个小的外部应用程序来关闭当前正在运行的进程，安装更新程序，并重新启动新版本。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|77231|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Are you trying to update while the application is running? If so, it will not be possible. You need to think of a better way, like using a small external app to kill the current running process, and install the update, and restart the new version.

blocks|key|205794|text|您可以尝试在解决方案上进行重建。你在的时候也可以打扫它。如果您更改的只是内容文件，我可以看到这种情况是如何发生的。如果没有，那就置之不理。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|205795|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You might try doing a rebuild on the solution. You could also clean it while you're at it. I can see how this would happen if all you changed were content files. If not, then disregard.

blocks|key|77277|text|应用程序的可执行文件可能不会更新，因为您没有增加MFC项目中的版本信息资源。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|77278|仅仅增加安装项目版本是不够的。见下文：|77279|http://msdn.microsoft.com/en-us/library/6fkzft86.aspx|offset|length|77280|“安装API也使用版本信息。”|77281|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|0|1H|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|S|8|@]|9|@$F|T|G|U|1|V]]|A|$]]|$1|H|3|I|5|6|7|W|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|X|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|E]]]]

Your application's executable may not be updating because you did not increment the VERSION information resource in your MFC project. 

It's not enough to just increment the setup project version. See below:

<a href="http://msdn.microsoft.com/en-us/library/6fkzft86.aspx" rel="noreferrer">http://msdn.microsoft.com/en-us/library/6fkzft86.aspx</a>

"Version information is also used by setup APIs."

blocks|key|205982|text|在我的头撞了几个小时后终于弄明白了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|205983|我的问题和这个问题是一样的，结果很容易解决。上面的两个答案使我走上了正确的方向，帮助我解决了我的问题，但这里简单地说了一句。|205984|如果将RemovePreviousVersion设置为true，则在程序集信息按钮下的应用程序设置中最有可能出现问题。|205985|我运行了mohlsen在上面的答案中显示的日志，msiexec+/i+"project.msi“/l*v+"c:\install.log"，最后得到了相同的响应，不会覆盖；不会修补；现有文件具有相同的版本。|offset|length|style|BOLD|205986|逆给我指明了正确的方向，但也使我对MFC引用产生了一些影响。我正在编写一个windows应用程序，最后将两个和两个放在一起，然后转到我在Application选项卡下编写的应用程序的属性。有一个按钮名为程序集信息，它将导致程序集版本和文件版本。我增加了这些，现在是我的.exe文件更新。|205987|因此，您必须做两件事，在您正在编写的应用程序中增加实际的程序集版本，以及安装包的版本。|205988|entityMap^0|0|0|0|4|7|O|19|29|J|0|0|1|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|S|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|U|8|@$H|V|I|W|J|K]|$H|X|I|Y|J|K]|$H|Z|I|10|J|K]]|9|@]|A|$]]|$1|L|3|M|5|6|7|11|8|@$H|12|I|13|J|K]]|9|@]|A|$]]|$1|N|3|O|5|6|7|14|8|@]|9|@]|A|$]]|$1|P|3|-4|5|6|7|15|8|@]|9|@]|A|$]]]|Q|$]]

Finally figured this out after banging my head against the wall for hours. 

My problem was identical to this one and ended up being very simple to solve. Two answers above led me in the right direction and helped me figure out my problem but here it is in a nutshell.

If you have RemovePreviousVersion set to true then the problem is most likely in the application settings under the assembly information button.

I ran the log as mohlsen showed in the answer above, msiexec /i "project.msi" /l*v "c:\install.log" and ended up with the same response, Won't Overwrite; Won't patch; Existing file is of an equal version

Inverse pointed me in the right direction but also threw me off a bit with the MFC reference. I am writing a windows app and finally put two and two together and went to the properties of the app I am writing under the Application tab. There is a button called Assembly Information that leads to the assembly version and file version. I incremented these and now my .exe file updates. 

So you do have to do two things, increment the actual assembly version in the app you are writing as well as the version of the install package.

blocks|key|77302|text|另外一个提示:如果您打开项目的AssemblyInfo.cs文件，并将AssemblyVersion更改为|type|unstyled|depth|inlineStyleRanges|entityRanges|data|77303|汇编:+AssemblyVersion("1.0.*")|77304|然后，每次生成项目时都会自动更新程序集版本信息。然后注释掉或从同一个文件中删除AssemblyFileVersion条目，因此文件版本默认为程序集版本。这意味着每次构建文件时，文件版本都会自动更新，因此您只需更新安装程序版本就可以得到您预期的文件覆盖。|77305|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

One additional tip: if you open the AssemblyInfo.cs file for your project, and change AssemblyVersion to

[assembly: AssemblyVersion("1.0.*")]

then the assembly version information is automatically updated each time you build the project. Then comment out or remove the AssemblyFileVersion entry from the same file, so the file version defaults the same as the assembly version. This means the file version updates automatically each time you build it so you only have to update the installer version to get files overwritten as you're expecting.

I have a Winforms project with a single .exe file as the primary output. I'm using a deployment project to distribute it, but the .exe file is not being updated when the new version is installed, meaning I have to ask the users to manually uninstall and then install the new version.

Here's what I'm doing:

<ul>
<li>I increment the assembly version on the output project (which is the primary output of the deployment project)</li>
<li>I increment the deployment project version (and update the product code when prompted)</li>
<li>The deployment project is set to remove previous versions</li>
<li>the 'Permanent' property on the .exe is set to False</li>
</ul>

I'm sure I've done this before successfully, but I can't seem to do it now. What am I doing wrong? 

Edit: I got it to work by changing the file version in the project properties, as in <a href="https://stackoverflow.com/questions/511789/how-do-i-persuade-a-vs2005-msi-to-upgrade/1510353#1510353">this answer</a>
