After installation a new standalone version of SCIA Engineer, the licence for an older version is lost.
If you installed a new version of SCIA Engineer, the licence will be lost for an older version. So, this means – if you still plan to use the older version of SCIA Engineer - that you have to update the license for this older version with the new licence.
So, if you licence the new version, then you have to licence the old one with a NEW .lic file afterwards.
To update a SCIA Engineer licence file for SCIA Engineer 2010.0 and newer, open the Protection setup (under "Programs -> SCIA Engineer -> Licence Manager" or by means of "lockman.exe" in installation folder of this older version) and click ‘Import licence file’. This will update the current licence to the new SCIA Engineer version.
