Note: In future versions of SetupBuilder this should be as easy as checking an option box, but for now you need to do it manually as follows.
In SetupBuilder, click the "Script Editor" tab on the right side of your screen:
This changes you to the script view in SetupBuilder.
Next locate this section of the script:
Double-click the "Include Web Update Client" line to open this screen:
Click the file dialog button. Then navigate to the SetupCast Enhanced Web Update folder (above) and down into the folder and select the wupdate.exe file as shown here:
Click Open to return to the script editor dialog and this screen:
Click Ok to return to the script view.
Your script will now look like this:
That is all there is to it!
Your SetupBuilder project will now distribute the Enhanced Web Update client with your installer.
When the client checks for updates it will look for a file called setupcast.rtf that will be published by SetupCast in the webupdate folder.
Note: If the "setupcast.rtf" file can not be located, the Enhanced Web Update client will "fall back" and use the default "A new version is available" screen of the regular SetupBuilder client.
