open it via a web page or from your local?

if from a web page, you need to have appropriate permission to allow to access to your local resources, then may use javascript like this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Untitled Document</title>
</head>
 
<script language="javascript">
	function exec (command) {
	  if (document.layers && navigator.javaEnabled()) {
		window._command = command;
		window.oldOnError = window.onerror;
		window.onerror = function (err) {
		  if (err.indexOf ("User didn't grant") != -1) {
			alert('command execution of ' + window._command + 
				  ' disallowed by user.'); 
			return true;
		  }
		  else return false;
		}
		netscape.security.PrivilegeManager.enablePrivilege
	('UniversalExecAccess');
		java.lang.Runtime.getRuntime().exec(command);
		window.onerror = window.oldOnError;
	  }
	  else if (document.all) {
		window.oldOnError = window.onerror;
		window._command = command;
		window.onerror = function (err) {
		  if (err.indexOf('utomation') != -1) {
			alert('command execution of ' + window._command + 
				  ' disallowed by user.'); 
			return true;
		  }
		  else return false;
		};
		var wsh = new ActiveXObject('WScript.Shell');
		if (wsh)
		  wsh.Run(command);
		window.onerror = window.oldOnError;
	  }
	}
 
</script>
 
<body>
<p><a href="#" onClick="exec('C:\\test.chm');return false;">Launch File</a> 
</p>
<p>Security Tab &gt; Custom Level</p>
  <p>A window Prompted out (Security Settings)</p>
  <p>Enable the setting of &quot;Initialise and script ActiveX controls not marked as safe&quot;</p>
  <p></p>
</body>
</html>

Open in new window

By default, the viewer for CHM file should have been loaded on your computer already.  If when you double click on the file and it doesn't display on screen, try downloading the HTML HELP Viewer from Microsoft here: http://msdn.microsoft.com/en-us/library/ms669985.aspx

Do you have proper permission on your browser?

if you using IE, try go to Menu Tools > Internet Options, then:

Security Tab > Custom Level

A window Prompted out (Security Settings)

Enable the setting of "Initialise and script ActiveX controls not marked as safe"


if necessary, close all browsers then retry again...

I changed the permissions but still could not get the file to open.

I have now managed to get it working with the method suggested by jaydee-cdgp with a rt click on the option Open with HTML Help Executionable

So thanks every one for your valued support

Method 1
Double-click the .chm file.
In the Open File-Security Warning dialog box, click to clear the Always ask before opening this file check box.
Click Open.

Method 2
Right-click the CHM file, and then click Properties.
Click Unblock.
Double-click the .chm file to open the file.
