Quick Install To install Simple UnZipper copy simpluzp.exe to your windows directory and diskstuf.dll to windows\system. Check your windows\system subdirectory for a file vbrun300.dll if you do not have a copy you must get one from any BBS or online service, it is usually stored online as vbrun3.zip. You should then put a copy of pkunzip.exe in a directory in your path statement, I suggest C:\dos.
