I was hoping it fixed the issues with updating the ATi Catalyst drivers (I can't update them while WB is active)

You must own Object Desktop, not just Windowblinds.

Be sure that you have ObjectDesktop registered in Impulse.  Click on the Impulse Orb (top left) and select 'Register a product...'. In the screen that opens check to see that ObjectDesktop is registered and if not then click 'Add Registration' at the bottom of the screen and enter the information you received in the email from Stardock after your purchase.

If that doesn't resolve your issue then please email support@stardock.com and they will get this fixed for you.

This should be OK,or not?

For the people that have problems with the installation of WB 7 (code registration is not valid), i've resolved in this way:

Go in Update Tab

You see wb 7, now don't click update in the bottom part of impulse but in the right-top part there is a button "Install all updates", click this and the installation start

Strange but true

This link has what is included in the different versions of ObjectDesktop -

I had a bit of difficuty instaling WidowBlinds 7 too.  I do not have Object Dock.  I have WindowBlinds and SkinStudio 6.  What I found after a bit of fiddling around was that I had missed a recent update to WindowBlinds 6.  Once I right clicked on WindowBlinds 6 and ran the update, it installed the new version 7 without a problem.  You might want to check and make sure you haven't missed an update to Object Dock as that could cause the same problem I had.  Hope this helps.
