RealCost is designed to run in Microsoft Excel 2000 and is not supported by versions earlier than Excel 2000. In addition, up-to-date service packs for Windows and Office 2000 (or Excel 2000) are essential to run the software.
Following are the recommended minimum system requirements for using RealCost:
To install RealCost, run the file, "Setup.exe." It is recommended that you allow the installation program to install the software to its preselected location. Setup.exe contains an Excel 2000 workbook file named "RealCost.xls" and several dynamic link library (DLL) files. A DLL is a collection of small programs that can be called upon when needed by the LCCA worksheet. The DLL provides instructions to the LCCA worksheet to carry out particular functions.
