You can upgrade to this version of Oracle IRM Desktop from version 5.5 onwards, by running the installation wizard on the computer that has the older version.
For versions earlier than 5.5, or from any version of SealedMedia Unsealer or Desktop, you can upgrade to this version only by uninstalling the older version and installing this one.
Caution:When upgrading from an earlier version of Oracle IRM Desktop, you will lose the rights that are stored locally to use sealed documents (the rights that enable you to continue working when you are offline). When this happens, you will have to obtain new rights by going online and synchronizing with the server. For this reason, do not begin an upgrade unless you have online access to the server. (You can cause resynchronization by opening an existing sealed file.)
