问题描述

我目前正在开发一个具有Setup Installer项目的C#项目.在安装过程中，是否有任何方法可以访问复制的MSI文件的路径(特别是名称)(该文件将缓存在C:\ Windows \ Installer中)?

我希望将此文件存储在文本文件中的某个位置，以便能够直接从表单中卸载我的应用程序.

解决方案

卸载 :无需直接访问该文件，有很多方法可以不使用缓存的文件名进行卸载:

I’m currently developing a C# project that has a Setup Installer project. During the installation process, is there any way to access the path (especially the name) of the copied MSI file (it gets cached in C:\Windows\Installer) ?

I would like to store this somewhere in a text file in order to be able to uninstall my application directly from within a Form.

解决方案

Uninstall: There is no need to access that file directly, there are plenty of ways to uninstall without using the cached file name: Uninstalling an MSI file from the command line without using msiexec.

The easiest is just to uninstall by product code:

msiexec.exe /x {PRODUCT-CODE-1111-1111-11111111111X}

And you can uninstall by upgrade code (2), or by name:

• WIX (remove all previous versions)

You are not trying to uninstall the application that is running from its own GUI are you? :-) Breaking the law. Breaking the law. Wouldn't try that.

LocalPath: There are also several ways to retrieve that local cache path via the MSI API:

On Error Resume Next
Set installer = CreateObject("WindowsInstaller.Installer")

' The product name you search for:
search = "Windows SDK EULA"

For Each product In installer.ProductsEx("", "", 7)
   name = product.InstallProperty("ProductName")
   cachepath=product.InstallProperty("LocalPackage")
   If name = search Then
      MsgBox name + ": " + cachepath
      Exit For
   End If
Next
