I have made the switch to 64 bit Vista and all the drivers I need are now available. I don't know if it's me but 64 bit seems to run smoother and so far there has been only 2 programs that I have been unable to install. Most install under the Program files x86 folder and run good. But all this could be due to the fact that I am using a rather high end new hardware machine...........

well, right now I am using the 5.51.025 version of WB and it works just fine. Log on Vista works, as does Deskscapes. Icon packager is so-so,and Cursor XP works just fine. WinCustomize browser and Stardock Central work as advertised. Tweak Vista is ok and Component tray does what it should. That is all I am running at the moment. I have Object Dock Plus installed but I have yet to work with it. Hope this helps  

I made more or less the same experience with Vista64;

Most non-Stardock programs run fine, although finding a Firewall for Vista64 was a bit hard (there are still only a few out there).

As for the Stardock products:

ObjectDock: runs fine (didn't use the systray though)
Windowblinds 5.51.025: runs without a hitch
Deskscapes: no problem
LogonVista: no problem
TweakVista: I'm not sure about that, but I suspect that not all changes I make are actually "sticking".
IconPackager: had to uninstall as I lost all Icon-associations of my .exe-files (restoring the Icon-Cache didn't solve the problem). Furthermore, it didn't seem to change any of the dynamic folders.
CursorXP: didn't dare to install (might try it now after raisinjack's post)
RightClick: simply doesn't show when started - Still waiting desperately for an update!

I guess all the folks using 64bit OS's must be offline...........?
