2.2
Upgrading to a new version
A newer version of the installer may be run which will detect the presence of the previous version
and allow a user to upgrade to a newer version. The current configuration of any drivers installed
will be maintained to avoid the need repeat previous encoder settings:
2.3
Reinstalling the same version
After initial installation, the same version of the installer may be run again to allow a user to perform
a repair, removal (preserving configuration) or uninstall the driver:
2.3.1
Repair
This selection allows a user to reinstall the driver components. The current driver configuration
information is maintained so that a subsequent installation will not require these settings to be
reentered.
2.3.2
Preserve Configuration
This selection allows a user to remove all driver components while maintaining the current driver
configuration information so that a subsequent installation will not require these settings to be
reentered.
