                    {
                        Console.WriteLine(versionNumber);
                    }

Answer 2

The only solution which works for me is:

    var adobePath = Registry.GetValue(
@"HKEY_CLASSES_ROOT\Software\Adobe\Acrobat\Exe", string.Empty, string.Empty);

Then I check if adobePath != null then Adobe reader is installed.

This way I will get also the path to the acrobat reader executable.
