As stated in the Adobe Support Lifecycle Policy, Adobe provides five years of product support, starting from the general availability date of Adobe Reader and Adobe Acrobat. In line with this policy, support for Adobe Acrobat Classic 2015 and Adobe Acrobat Reader Classic 2015 ends on April 07, 2020.
In order to best support our valued customers, the end of product support for Acrobat Classic 2015 has been extended to July 7, 2020.
End of support means that Adobe no longer provides technical support, including product and/or security updates, for all derivatives of a product or product version (localized versions, minor upgrades, operating systems, dot and double-dot releases, and connector products).
Subscription plans are the best way to take advantage of everything Acrobat has to offer. New annual and month-to-month subscription plans make Acrobat more affordable than ever, while also giving you access to premium Adobe Document Cloud services.
