You can overwrite the existing JP1/Software Distribution program with the same or a newer version of the program. By installing the same version, you can change the installation settings or restore the original settings. To change or correct installation settings by overwriting the same version, use the maintenance wizard; for details, see 1.3 Changing installation settings.

The programs that can be overwritten depend on the installation target system. The following table shows the programs that can be overwritten by target system:
