Next, you must remove the existing version. Select the Start button and
then Settings>Control Panel>Add/Remove Programs. For Euronav

Euronav Charting System must be uninstalled.
Run Windows Explorer and make copies of following files in the Data
subdirectory (see page 12.5) to somewhere other than the Deckman
directory:
Adjvt.d wind speed calibration
adjwa.d wind angle calibration
bgbounds.d B&G instruments data bounds
Bgcalib.d Calibration
Bgdamp.d Damping
bgout.d Output
databar.d Data bar settings
diamonds.d Tidal stream data
j_nav28.d Layers information
j_way.d Waypoints file
Navpol.d Navigation polar
Ockcalib.d Ockam instruments Calibration
Ockdamp.d Damping
ockoptn.d Options
ockout.d Output
Perfpol.d Performance polar
report.d Reports file
shore.d Shoreline information
Startpol.d Start polar
Tides.d Tidal heights data
Once all these files are backed up, delete the Deckman directory (before
doing this, it is just worth checking that no charts have been installed
here: chart directories should be as described in ‘Installing Charts’
above).
