I've been looking at the version numbers as reported by the Windows "Add or Remove Programs" > "Click here for support information" and they don't match the real versions.
Examples:

SiteSpinner V.2.70.e shows 2.16

Web Engine V2.00L Beta shows 1.08

Web Dwarf V2.50.f shows no version information

There might be a very good reason for this, or it might be a bug -- I don't know which

Not that is not a bug Brucceee. That is the installer package version number rather than the product version. We are going to try to keep in in sync with the program version going forward. So 2.70e will be 2.70.5 (i.e 'e' =5th letter) and so on. Packages prior to 2.7 don't use the microsoft installer engine and so don't show a verion number.
