Additional Support Resources for 20:21 Library CD #1 - Main Library
Support Status

Known Issues
The FoxPro 2.6 runtime used for the main menu fails on startup, usually with a divide-by-zero error. This problem generally occurs with CPU speeds above 333MHz, and is described in Microsoft knowledge base article Q240982. In case of problems using the Microsoft site, a PDF version of the article and a download of the needed patch file are available here.
Most problems on Windows NT-based platforms (4.0, 2000, and XP) are caused by inadequate user write permissions in the installation directory tree (by default C:\2021LIB). In general, users must have full read-write-create access to the full directory tree.
