The is a required engine for running 64-bit Office-based solutions developed with Visual Studio. Despite the "2010" name, it remains the modern runtime required for add-ins in newer versions of Office, including Office 2019, 2021, and Microsoft 365. Core Functionality

: The x64 version specifically runs solutions in 64-bit editions of Office . Note that if you have a 32-bit edition of Office on a 64-bit Windows OS, you still need the x86 version of the runtime.

You cannot mix and match. A 64-bit instance of Excel cannot load a runtime loader designed for 32-bit architecture. This is often the primary cause of "Add-In failed to load" errors in enterprise environments. A system microsoft visual studio 2010 tools for office runtime -x64-
