DeskScapes 2.0 works 100% even after a reboot on Windows 7 RC 64 bit.
Well it's been a few days since it's been released and Orbit30 has worked his magic again. You'll need his PlusPatch 10 to install Dreamscene (manual file copying required for 64 bit), then without rebooting install Deskscapes 2.0.
It told me it needed a reboot, but before that I tested (and activated) it which went fine as before - and even after a reboot .dreams are still working. Happy days.
