Let's look at some facts...
1. Several Boot Logo programs worked until the release of Vista SP2
2. Vista SP2 was released on or around 26th. March 2008
3. Stardock's pathetic attempt was released on or around 19th. November 2008
4. It is now the 21st. January 2009, and still many people around the world are unable to get this program to work. (March 2008 to now, to get the program to work)
It should never have seen the light of day until it at least worked on all Vista systems, and then perhaps patches released to improve the product.
It at best has been an "Alpha" release, and Stardock should approach Microsoft for some answers or assistance as to how to remedy the situation, after all, they have claimed on several occasions that Microsoft endorse their attempts to imrpove the GUI and other appearance programs. eg. Window Blinds, Vista Logon, CursorFX etc.
People have paid good money, and deserve better support than they are getting.
