Activating/Upgrading a License
When upgrading software versions (ie. from v8.50 to v8.60), it is not necessary to uninstall the previous version prior to installing the upgrade.
Software-based license users please note: it is imperative that you return your previous version license (via the Local License Manager utility) prior to activating the upgrade license; otherwise, you will encounter the operations error: 7288.
Note: upgrade licenses are also not limited to the number of returns/activations granted one instance of the license is active at a given moment.
