FIX: Daemon Tools for .MDF image mount in Windows 7
Do this:
1. Download latest SPDT drivers here: Link Removed
* Don't worry if it doesn't list Windows 7 as a supported platform, it still works
* Reboot after install
2. Install Daemon Tools Lite
* That's it!
Tried all kinds of software (Magic ISO, Power ISO, Ultra ISO, etc) before I found this fix.
