I am using Setup Factory 7 to make the installer but the compression ratio is more than 50%, so I am trying to use 7Zip with Setup Factory 7 I am thinking of running an exe file of the 7zipped-firefox and extract to TEMP, then use Setup Factory to copy the folder of Firefox to Program files. But now I can't make the exe file of 7zipped-firefox auto extract, it always show dialog box of where it will extract to. how to solve this? And, any better installer builder than setup factory?
