In order to update TILIGO program, you need to download DEMO version (newer than the one installed) and reinstall the program. The installation program will detect the older version on a given computer and it will update the program without deleting existing data.
If you update DEMO version, an updated program will also work as DEMO version. The number of days remaining to the end of the trial period will be the same as before the update. If you update the licensed program with a new DEMO version, the updated program will remain licensed.
The update of DEMO version is always free.
