I recommend CabTool for making your cab files: http://www3.sympatico.ca/lazimute/CABTOOL_SETUP.ZIP And also use scripts for putting it in your SendTo folder: http://www3.sympatico.ca/lazimute/CABTOOLS.ZIP Sorry if this seems like an advertisement. How to repack an installer (reduces size - if you have multiple files with your installation, also use this method) For this you need WinRAR. First, select all of the files needed for your installation and right click, go to add to archive.. Check SFX Archive. Go to the Advanced tab and press SFX options. In the run after execution box, type the name of your setup file and any switches you need for it to be silent. Go to Modes. Check unpack to temporary folder. Also, press Hide All. Now just press okay twice, and you'll have your packed completely silent setup file! Hope this helps.
