As I can see the first code snippet from your question calling Help.ShowHelp isn't so bad. Sometimes I'm using the related code below. Many solutions are possible ... Please note, typos e.g. somehting.chm are disturbing in code snippets.

private const string sHTMLHelpFileName = "CHM-example.chm";
...

private void button1_Click(object sender, EventArgs e) {
  System.Windows.Forms.Help.ShowHelp(this, Application.StartupPath + @"\" + sHTMLHelpFileName);
  }

So, please open Visual Studio - Solution Explorer and check the properties of your CHM file. Go to the dropdown box shown in the snapshot below and set "Always copy" (here only German). Start your project in Debug mode and check your bin/debug output folder. Do the same for Release mode and output folder. The CHM should reside there and I hope your CHM call works.

Answer from similar topic is:

// get full path to your startup EXE
string exeFile = (new System.Uri(Assembly.GetEntryAssembly().CodeBase)).AbsolutePath;

// get directory of your EXE file
string exeDir = Path.GetDirectoryName(exeFile);

// and open Help
System.Windows.Forms.Help.ShowHelp(this, exeDir+"\\"+"somehting.chm");

You need : 

String exeDirectory = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location);

So :

String HelpFilepath = "file://" + Path.Combine(exeDirectory , "somehting.chm");
Help.ShowHelp(this, path);
