This is a version of LcdWriter for x64 Vista. Thanks to Myst for helping out with this.
Before installing this, you must disable driver signing. To do this open an elevated command prompt and type “bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS”, then reboot.
I don't have an x64 system to test this on, so it's untested. If you have trouble making it work take a look at this thread.
