Thank you for trying PC-ECAP It is necessary to install PC-ECAP before you can use it. Because PC-ECAP needs to create data files when it runs, it is not possible to run the program directly from a CD-ROM. To make installation very easy, an INSTALL program has been included. To install PC-ECAP just type: INSTALL PC-ECAP may be installed to either a hard drive or a floppy diskette.
