Note: version 4.20 modifies the structure of the database. The adjustment is made automatically when this version is first started, but before that the program prompts you to make a mandatory backup of the database. If you use the program "on the network", you can only make the backup on the computer where the database is physically located. So run the newer version first on the server and log in to the database as "local". After updating the database, you can connect to it even from client computers.
If you are using Cutting Assistant or Edging Assistant, you need to download and install their latest versions as well.
Note: if you are using the Cutting Assistant, please download its latest version 1.10 and resubmit the production batches in the new version of Optimik.
WARNING: if you also use a Firebird server, download and install the newer version 3.0.7. If you install it in another folder (or change the password), you will need to reconfigure it. See the quick start guide for more information.
