Adobe’s strategic shift to the DC subscription model makes Acrobat Pro 2020 an anomaly. Subscription versions require periodic online check-ins (typically every 30–99 days), making them incompatible with fully offline environments.

However, this comes at a cost: no access to cloud-based features (Document Cloud storage, e-signature services, or collaborative reviews) and eventual obsolescence as operating systems evolve beyond the software’s compatibility.
