Baker’s Software
Clunky by today’s standards but extremely effective
Cannot be used to analyseone’s own data
Creates too many windows – sometimes better to shut it down and re-open
Be patient with it and you’llbe rewarded
Can be downloaded from http://echo.edres.org:8080/irt/baker/software.htm
Download the accompanying software (400KB) (You can download and run this program later or you can run this program from its current location.)
Download BIRT setup.exe
MSVBM50.DLLThe software requires the Visual Basic 5.0 run-time package, Msvbvm50.dll,
which may already be on your computer typically in the c:\windows\system\ directory. If not, you can obtain the full 1.24 megabyte support package from
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q180071
Or, you can download a 650KB install program for msvbm50.dll from us. This program should go in the system directory (typically c:\windows\system).
Download vb5run.exe
MSFLXGRD.OCXThe software also requires MSFLXGRD.OCX which may not be on WinXP
computers. You can download the file here. It would go either in the same area as Dr. Baker's software or in your c:\windows\system32 area.
MSFLXGRD.OCX
