In the stand alone, when you click HelpAbout what version does it say just above the copyright notice? The actual version will also be printed out when you click the HelpVersion menu. You'll need to scroll the status window text up a little to see it.

In the plug in click the Version button. The version number will be displayed just above your registration details.

Everywhere else its just a generic Wardrobe Wizard 2 to differentiate it from Wardrobe Wizard 1
