What is the End-Of-Life (EOL) for the Microsoft Office Suite (Excel, Powerpoint, Word, etc.) with respect to Qlik Products, such as Nprinting Designer, Qlik Sense, Qlikview, etc.?
Qlik does not set End-Of-Life policies independently from Microsoft; if Microsoft supports the version of Office used by your organization, then Qlik also supports that version of Office**.
See Microsoft's Support Site for detailed release/support information from Microsoft.
** Note that Office365 is not supported for Nprinting Designer (see Is Office 365 supported in Nprinting Designer, and are there any known issues or incompatibilities? for more information)
