This method works for any executable located in a folder which is defined in the windows PATH variable:

private string LocateEXE(String filename)
{
    String path = Environment.GetEnvironmentVariable("path");
    String[] folders = path.Split(';');
    foreach (String folder in folders)
    {
        if (File.Exists(folder + filename))
        {
            return folder + filename;
        } 
        else if (File.Exists(folder + "\\" + filename)) 
        {
            return folder + "\\" + filename;
        }
    }

    return String.Empty;
}

Then use it as follows:

string pathToExe = LocateEXE("example.exe");

Like Fredrik's method it only finds paths for some executables
