How to find a (ie., Portable single executable) software requires a particular OS (Win98, Win98SE, WinME, Win2000, WinXP, Linux). I am using Win98SE in one pc and WinXP in another PC. If I copy/install a portable software or package in win98se, only after installing / executing that software, that program tell us it requires WinXP,. Is any software to find a particular software needs to run only in win98SE or greater. I tried Dependency Walker by Steve Miller but no results. Kindly help to solve this problem.
