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


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.
