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 10.x and Adobe Reader 10.x ended on November 15, 2015.
End of Support means that Adobe no longer provides technical support or distributes runtimes. This policy affects product and 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).
Adobe strongly recommends that customers update to the latest versions of Adobe Acrobat Reader and Adobe Acrobat. By updating installations to the latest versions, customers benefit from the latest functional enhancements and improved security measures.
