以编程方式检测是否已安装Windows Media Player [英] Programmatically detect if Windows Media Player is installed

问题描述

有人对如何以编程方式检测是否安装了Windows Media Player有任何建议吗?

Anybody have any advice on how to programmatically detect if Windows Media Player is installed?

我知道要查找注册表设置，但是不信任它，因为它可能会引起误解(未安装可能不会将其删除).而且我考虑过只是发布视频，但是由于未安装Media Player可能会导致错误，因此也不是确定性的.

I know about the registry setting look up, but don't trust it since it's more than a little misleading (uninstalled may not remove it). And I've considered just launching a video, but an error could be caused by something other than Media Player not being installed, so it's not conclusive either.

理想情况下，我希望可以在我的C ++应用程序和我的 NSIS 中使用的解决方案安装程序.但是我的C ++应用程序是最重要的，我愿意忍受安装程序中的注册表黑客攻击.

Ideally, I'd prefer a solution which could be used from both my C++ application AND my NSIS installer. But my the C++ app is the most important, I'm willing to live with the registry hack in the installer.

推荐答案

查看键HKLM\Software\Microsoft\Active Setup\Installed Components\{22d6f312-b0f6-11d0-94ab-0080c74c7e95}下的IsInstalled值.如果已安装，则为1，否则为0.

Look at the IsInstalled value under key HKLM\Software\Microsoft\Active Setup\Installed Components\{22d6f312-b0f6-11d0-94ab-0080c74c7e95}. It is 1 if installed, 0 otherwise.
