>The installation program installs foxtools.fll into the directory where the program is located. I've tried copy into the directory again to make sure that it wasn't a bad copy in there, but it still didn't fix the problem..

FOXTOOLS.FLL requires several other system .DLL's to be present on your system. You're probably missing MSVCRT.DLL from your WINDOWS\SYSTEM folder, or maybe WSOCK32.DLL. All the other .DLL's it references seem to be pretty standard. I've had the missing MSVCRT.DLL problem before.
