The best solution for doing updates in your software is to use TrueUpdate. I wouldn't put it past AMS to do what you're talking about, but TrueUpdate is definitely designed to do exactly what you're talking about. You know what they say... The right tool for the right job...

Maggie,

Although I would agree with eric_darling about True Update being a better choice for the job I would like to offer the following information.

I made a simular program that would check the web for any updates to the current program. What it would do was...

1. Check for internet connectivity
2. Get the current version of my program (example 1.0)
3. Download a text file that is entitled the current version of the program I'm updating. for example "Myprogram_1.0.txt".
Note: In this file I have the version to upgrade to and any message that I might want to display. Maybe added features or special requirements.
If there was no update the file would have the same version as the current.

example
1.2

Updated GUI
Fixed problem with Windows 98 OS
...
...


4. Compare the versions to determine if an upgrade was available.
5. Download the upgrade
6. Run the upgrade (which changes the current version info in the registry for example)

Now when you check for upgrades again you may or may not have additional upgrades to install. Based on the way I was doing this I would include all the minor upgrades in my major upgrades so you can just download one. This may be a larger size.

You may want to add file CRC checking and ensure the user has enough space on the harddrive. Hope this helps a little.

Here is a snippet of code from my project.

--Set vars
storage_path = "C:\\MyProgram";
CurrentVer = "1.0";
WebAddress = "www.indigorose.com";

-- Check to see if the user is connected to the internet
connected = HTTP.TestConnection(WebAddress, 20, 80, nil, nil);

-- If they are connected.
if connected then
	Paragraph.SetText("Paragraph5","Checking for newer version...");
	HTTP.Download(WebAddress .."/Downloads/MyProgram_"..CurrentVer ..".txt", storage_path .."\\version.txt", MODE_TEXT, 20, 80, nil, nil, nil);
	--open version file from web and compare to current version
	version = TextFile.ReadToString(storage_path .."\\version.txt");
	isBigger = String.CompareFileVersions(version, CurrentVer)
	
	if isBigger == 1 then
		--Get updated message file from web
		HTTP.Download(WebAddress .."/Downloads/MyProgram_" ..version .."msg.txt", storage_path .."\\" ..version .."msg.txt", MODE_TEXT, 20, 80, nil, nil, nil);
		newMessage = TextFile.ReadToString(storage_path .."\\" ..version .."msg.txt");
		--display message or features
		Paragraph.SetText("Paragraph3",newMessage);
		Paragraph.SetText("Paragraph5","A newer version is available.");
		--Enable the continue button
                          Plugin.SetEnabled("Plugin1", true);
		Page.SetFocus("Plugin1");
	else
		Paragraph.SetText("Paragraph5","You have the newest version.");
	end
else
	-- if they are not connected
   	Paragraph.SetText("Paragraph3","Unable to connected to the Host Server. Please check your connection or try again later.");		
end

in the continue button download the actual update and run it.
