The Wise Installation System creates and edits Windows Self-Installing Executables. It uses an installation script to determine which files to install and where the files are copied to. The resulting executables can be directly uploaded to a BBS or other On-Line service. The end-user does not need any software (other than Windows itself) to install the Wise executable. When they run the program under Windows, the program extracts the files from itself and installs them onto the client system.
