Uninstall whatever WB versions you have installed and then use the Object Desktop's Component Manager to install WB 4. (If you purchased a standalone WB license on or after January 1, 2003 you can get WB 4 via a direct download via this page: https://www.stardock.com/support.asp . Otherwise a standalone license for the WB4 upgrade costs $10) Since you have OD, it's usually just easier to use CM to download/install since you already have a registered and current OD license.

Also, just to clarify since you're asking for a Stardock rep in this forum, you should know that this is not a Stardock support board. People here will pitch in to assist if they can, but this WC message board is for socializing and some help with WC/skinning stuff. If you want product assistance/support from Stardock you should email them directly.

Cool.
