V.8.7 isn't the latest one -> this would be V8.93 (and this one is really old too!).
Finally you should use some Patches from Brat or Harlekin (try some Search-Button's) to make W32Dasm kinda work. But this won't help u to go over some old Anti-W32Dasm-tricks, which will close down the disassembler, when starting it's work.
Good luck
