Are you setting the output directory first? (http://nsis.sourceforge.net/Docs/Cha...tml#setoutpath
). When a file command fails, usually it's because it can't write to that location (permissions or policies). What's the output directory? Also, this one or two seconds before it's closing, are you just doubleclicking the installer and touching nothing and it crashes one to two seconds later, or is it when it starts the install (entering the instFiles page)?
Usually hardware doesn't matter because NSIS is a full software based program (as opposed to using hardware accelerated code).
