• Confirm legal/licensing compliance for your chosen reader.
• Obtain installer from an official/verified source.

Adobe Reader XI is an unsupported, end‑of‑life product. It no longer receives security updates, so running it on machines exposed to untrusted files or the internet increases risk. Prefer modern, supported PDF readers where possible. If you must use XI, restrict its access to untrusted PDFs, isolate affected hosts, and use endpoint protections.
