Sage 50 - Statement
Sage will fully test and support all versions of Sage Accounts released after 29 July 2015 on Windows 10.
Sage Accounts 2013 (v19), 2014 (v20) and v21 were released before Windows 10, and have had limited testing. Sage can support you processing in your software, however, there may be issues that Sage can’t support you with. Sage therefore may be limited in what we can do.
