The is a critical software component required to run Microsoft Office-based solutions built using Visual Studio 2010 and newer versions. Specifically, the x64 version is designed for 64-bit editions of Microsoft Office, acting as a communication bridge between the .NET Framework and Office applications. What is the VSTO Runtime?

1. Audit all Office installations to document whether they are 32-bit or 64-bit.
2. Package the correct VSTO runtime (x86 or x64) in your software deployment tool (SCCM, Intune, PDQ).
3. Ensure all add-in manifests are signed with SHA-256 certificates.
4. Consider future migration to Office Add-ins for new projects, but maintain VSTO x64 for critical legacy modules.
