Upgrading to the current version of ViewNow X Server silently uninstalls the previous version, then installs the current version of ViewNow X. All user data is preserved, but installation features must be reselected. For example, if Central X Workspace Management was selected in the previous version and you want it implemented in this version, you must select it again during the installation process.
Had there been any items - X Workspaces (.xws files), X Servers (.srv files), or X Clients (.clt files) exported prior to upgrading, they should be re-exported upon finishing the upgrade.
