推荐答案

上面的例程将返回一个字符串，假设它找到了一个可能如下所示的匹配项:

The above routine will return a string, assuming it found a match that may look like:

MsiExec.exe/X{02DA0248-DB55-44A7-8DC6-DBA573AEEA94}

你需要把它当作一个进程来运行:

You need to take that and run it as a process:

System.Diagnostics.Process.Start(uninstallString);

注意它可能并不总是 msiexec，它可以是程序选择指定的任何内容.在 msiexec 的情况下，您可以将 /q 参数附加到您的 uninstallString 以使其静默卸载(并且不会显示那些修复/删除对话框).

Note that it may not be always msiexec, it can be anything that the program chooses to specify. In case of msiexec, you can append /q parameter to your uninstallString to make it uninstall silently (and it won't show those Repair/Remove dialogs).

更新:如果您使用的是 Windows 安装程序 3.0 或更高版本，您还可以使用 /quiet 进行静默安装/卸载.它与 /qn 基本相同(如果您使用的是旧版本).来源.感谢@JRO 提出它！

Update: If you're using Windows installer 3.0 or above, you can also use /quiet for silent install/uninstall. It's basically same as /qn (if you're on older versions). Source. Thanks @JRO for bringing it up!
