Can I install a Delphi version after my maintenance has expired?

Can I install and register a Delphi ISO I downloaded during my maintenance period, even after maintenance has expired?
Thanks in advance

Yes, you should be able to, I have done this many times. You may run into issues with activation limits if you have activated it too many times already… you will have to contact sales rather than support to get the limit bumped (support won’t talk to you without a subscription).
