Safety is a priority for enterprise software. The runtime includes deployment verification tools that check digital signatures. It ensures that an add-in has proper permissions before executing any code on your local system. Why is the 64-Bit Version Necessary? Purpose and Architecture : It provides the communication
Unlike VSTO solutions, which require local runtime installations like the x64 package and are confined to Windows desktop applications, modern JavaScript-based add-ins run cross-platform—across Windows, Mac, iPad, and web browsers—without requiring underlying local client runtimes. For existing infrastructure, maintaining the VSTO 2010 Runtime (x64) ensures that robust, locally-targeted automation frameworks continue to perform at maximum efficiency.
