从C＃VS2013中找到win 7中的安装路径（那里有exe文件，但当前未运行）

Question

From C# VS2013, I would like to get the whole path of an application that has been indtalled on win 7.

The post with 7 methods at:

   http://stackoverflow.com/questions/6041332/best-way-to-get-application-folder-path

cannot help me because I do Not need the path of the current running application.

I need the path of an application that has been installed (but currently not running ).

I have tried

  string [] allfiles = Directory.GetFiles(path, "*", SearchOption.AllDirectories) 

at

  http://stackoverflow.com/questions/23736343/recursive-search-for-files-in-root-directory-and-subfolders

But got:

 Additional information: Access to the path 'C:\Program Files\MSSomeApp\DATA' is denied.

My C# code:

 FileInfo executableFileInfo = new FileInfo("MyApplication.exe"); // It has been installed on win 7.
 string executableDirectoryName = executableFileInfo.DirectoryName;

This just returned my current VS2013 working directory. But, actually, "MyApplication.exe" was installed at C:\\MyPath.

I need to get the full file path C:\\MyPath\\, where all libs and exe files (of MyApplication) are there.

Any suggestions ? thanks

Well You can use something like:

    string[] paths = 
    System.IO.Directory.GetFiles(System.Environment.SpecialFolder.ProgramFiles,
 "MyApplication.exe", System.IO.SearchOption.AllDirectories);

This will look the Program Files Folder and all its Sub Folders for the file named MyApplication.exe and will return the full path of all of matches
