Can Acrobat 11 still be used?

This is helpful to know. I was wondering about older Acrobat versions on Windows 11 as well, especially when they were originally designed for much older systems. The compatibility issue makes sense, and it’s good to know that Acrobat 11 is no longer supported.

​@its50201495 I would not consider usng it as Adobe discontinued support and security updates for Acrobat 11 back in October 2017. Running it on Windows 11 Enterprise exposes your network to severe security vulnerabilities! 

If you wanted, you could buy a 3-year term license for Adobe Acrobat, specifically as a one-time upfront payment for Acrobat Pro 2024. It is a 3-year, non-renewing desktop software license purchased with a single upfront payment rather than an ongoing subscription. After the 3 year is up, you can buy another 3-year term license. It does not include Adobe Document Cloud services, web browser access, mobile app features, or AI capabilities. https://helpx.adobe.com/acrobat/faq-acrobat-pro-2024.html

One thing I should mentioned, don’t be fooled by the "lifetime" licenses—scammy sites! 

Hi its50201495,

Thank you for contacting us, and I apologise for the inconvenience you've experienced.

Please note that Acrobat 11 is an outdated and unsupported version. It has not been tested on Windows 11, so its compatibility is uncertain. For further information, please refer to the following help document: End of support for Adobe Acrobat XI and Reader XI.

Thanks,

Meenakshi
