CATIA V5: Transitioning from LUM to DSLS (CATIA V5R21)

This guide contains the steps required to change from LUM licensing to DSLS licensing. Note: Ensure CATIA is closed before transition.

    - C:\ProgramData\DassaultSystemes\Licenses\DSLicSrv.txt
    - Within DSLicSrv.txt  write the line <Server Name>:4085

2) Remove the DSLICENSING=LEGACY line from the CATIA environment file.


3) Make sure the client can see port 4085, either the Firewall needs to be disabled or an exception needs to be added for that port.

    Start > Control Panel > Windows Firewall

The machine should already have an existing Inbound and Outbound Rule which allows the machine to connect to the server via port 1515 to obtain a license.  This needs to be changed to 4085.

ii) SelectInbound Rules on the left pane then New Rule...
