On DSM 6, uninstall / reinstall is not required. You don’t gain anything by doing so.

On DSM 7, Uninstall / reinstall is solely to use the scripting built into the menus (which DSM 6 does not have)

For you, please look here at this procedure (DSM 6)

Let me know if you have questions.

ALSO, as FYI, might you consider DSM 7 ?
