Hi,
A quick question.
I am going to try out the new version before renewing my maintanance. I see that the installer defaults to overwriting the old version. Is this correct? Should I install in a new directory like "Alibre_21"?
You cannot have more than one version installed at the same time on the same computer.
You cannot run a trial on a machine where an activated install has been running. If you have current maintenance (expiry date after 8th April 2020) your licence will run v21.
