Go to the official Adobe Acrobat Reader download page and look for the 'Other Versions' or 'Older Versions' link.
Choose 'Mac OS' from the operating system dropdown menu, and select your specific older version (e.g., Mac OS 10.9).
Select 'Reader 11.0.10' from the version list, download the installer package, and double-click the file to complete the installation.
