bc62d.exe is a self extracting zip file(almost 10 meg) of the demo version of the BalCal program. It took 58:05 minutes to upload the file at 28 Kbps. Save it to some blank directory and then execute it. It should then extract about 321 files to that directory. Among all of those files is a file called SETUP.EXE. When you execute it, it will install the BalCal demo program to the default directory which is: C:\Program Files\BalCal62. You can then use the windows explorer to execute the BalCal62.exe program which is in that directory. Once you run it there are almost 3000 lines of help file comments available via the green help buttons on the various forms. They will explain in great detail each and every function of the program.
