You must run VFD as administrator or it won't work in Windows 7.
Here is a VFDWin version prepared for 64 bits, although you must configure it:
http://devel.archefire.org/vfd21-050404.zip
You need to do the following (I'll try to make a video showing it in YouTube):
- Run the dseo13b.exe file.
- Select the "Enable Test Mode" option.
- Now select the "Sign a System File", and type the full path to the "vfd64.sys" file.
- Sign the driver by pressing OK.
- Reboot the system to enable the changes.
- Open vfdwin.exe. Go to the "Driver" tab and type the full path to "vfd64.sys".
- Install it, then start it automatically (the "vfd64.sys" driver).
- Select any floppy image and use it normally.
By the way, make sure not to upload this file to a collection of yours of the Archive.org. If you do, it might break it for some illogical reason. So it would probably be better to upload files to individual Archive.org collection URLs and if they block or break the new collection, just don't download them to other existing collection.
