I´ve had big problems getting Vfapi to work. dRd advised me to run the vifpset.bat file from DOS-prompt. That didn´t work since it didn´t find the file (the ":"-sign doesn´t work in DOS-prompt for some reason). Neither did the install in "pure" DOS. Well, in the end it was pretty simple. I just right-clicked the vifp.ini-file and clicked install, after that everything was more or less gravy. This just as some advice if anyone runs into the same problem.
