I'am searching for Information / FAQ how to Update this Minor Versions? Do you have deinstall HD every time first or can you install over the current version?
Does settings and config loose (Windows vista 64)?
No need to uninstall, just install the new versions, it will create a new start menu item and keep your old prefs. You can safely uninstall the old versions anytime. Just be sure to not constantly reinstall the license server - that would only be done once.
it's possible that on your first try the newer version was configured to use local licensing, and only after reinstalling the license server it was reconfigured to use the license server.
