I got it working:
Mount with Daemon Tools, but don't do any of the disabling/deleting drives. After you mount, exit Daemon Tools in the system tray but leave Emulation options on. NWN2 should still be in your virtual drive but D-tools should not be running anymore and you can just run NWN2 normally now.
Edit: If it still doesn't work, here's a link to the 1.01 patch by itself (I'm assuming the game automatically updates to 1.02 now?) so that you can reinstall and not go straight to 1.02:
