do you mean from caesar 2019 or from 2018? and this "demo" version how much time works? forever or only 30 days? and do you need a key/dongle or you can use demo-version without anything?

question: opening a previuos version .CAESAR II with a newer caesar can damage the .CAESAR II model, can't it?
For example my client asked for caesar 2016 and i have all .CAESAR II 2016 models.

More: Last caesar version are HEAVY to load on old pc and sometime in offices the support drawers have slow pc. For this reason i was thinking to a light reader version, without many engines inside the complete caesar.
