To load a program from disk into memory once again in order to run it. Every time users launch an application, they are reloading it.
Contrast with "re-install." Re-install means performing the installation procedure over again from a CD or the Web. Reloading is common when the program crashes. Re-installing is much less common but necessary if program files have become unreadable due to damaged sectors on the disk or because files were accidentally erased or corrupted. This can also happen due to program error, in which the program erroneously writes incorrect data to some of its own configuration files.
