SYSTEM FILES 

            Question:

What can I do if RUMM2030 advises that one or more system files are missing.?

            Explanation:

Windows runs on a large number of different types of special files, usually called system files.  Sometimes one or more of these files become corrupted for all sorts of reasons, are shifted to a different folder unexpectedly (when using the mouse drag and drop technique, for example, a dangerous thing to do around folders with system files and therefore not recommended) or a file simply disappears!  In all such cases, an application involved with Rasch analysis will inevitably experience problems, including RUMM2030.

            Action:

• Because of the complexity involved with programs such as RUMM2030, the simplest solution in this case is to uninstall the program and then re-install again from the install CD provided with your purchase licence.  This ensures that all system files are correctly loaded and located on your computer.
• It is  a good rule of thumb that, when a Windows-based product experiences problems that do not appear to make sense despite trying a number of different work arounds, the uninstall/reinstall procedure is almost always successful.
