VFD is a very important piece of software for DOSBox and floppy inage cataloging. However, it was made for Windows 2000/XP, and some people have had trouble getting it to work on Vista and 7. Using Windows 7 64 bit, here are the problems and what I had to do to get it working:
First, using the current version (build 06-02-2008) of VFD, I got the message "Virtual Floppy Drive does not work on Windows 95/98/ME" when you start up vfdwin.exe. Nothing in the Properties menu would fix this and the program would not start. However, the prior version (build 04-04-2005) does not display the message and will start. Get the prior version from here:

Second, the driver will not start, presumably as it is a 32-bit device driver. To get it to start, first download the 64-bit driver here:

and replace the existing vfd.sys with it.
If you try starting this driver, Windows 7 will complain that it requires a digitally signed driver and will not allow unsigned drivers to run. Restart your system, press F8 as Windows is starting, and select the option Disable Device Driver Signing, and the driver will finally start. You have to do this at every boot up unless you use a more permanent way to disable digitally signed drivers.
