Extracting files form a Wise installer

[Invalid]

I know that Wise installers have the /s switch, but I'd like to know if its possible to extract the files from the installer. I've tried some zip programs (7-zip and WinRAR) but they can't. Does anybody know?

edit: it's and old fashon .exe installer by the way, not an .msi.

/X switch should do it
