Hello Donald, welcome to the forum!

You may know, Studio 2007 and Studio2009 are bundle promotional items, which includes Panoweaver professional and Tourweaver professional. You can upgrade your Panoweaver and Tourweaver to the latest versions separately. After upgrding we will send new licesne keys to you, then you can still use the older version, there are some different features the latest versions don't have, which will conitue bringing interests to your business.

If you can't afford the upgrade cost of both PW and TW at one time, then we recommend you to upgrade your Tourweaver 3.00 pro to TW4 pro as the priority,which will maximize the benefits for your virtual tour creating business.
