How to get Adobe Reader full path(including executable file name)?

it's possible? I need to get the full path of Adobe Reader including the executable name. I'm looking for on windows registries, the closer that I did was found the full path without executable name. Thanks in advance.

my code:

var adobe = Registry.LocalMachine.OpenSubKey("Software").OpenSubKey("Adobe").OpenSubKey("Acrobat Reader");var version = adobe.GetSubKeyNames().First();var path = adobe.OpenSubKey(version).OpenSubKey("installer").GetValue("path");

Thanks in advance.
