Microsoft product names and versions are subject to change. Always verify requirements with official Microsoft documentation.
After deploying vstor_redist_x64.exe, perform the following checks:
Despite its "2010" label, the x64 VSTO runtime is fully compatible with Windows 10, Windows 11, and Windows Server 2016/2019/2022. Microsoft has maintained backward compatibility through multiple Windows releases. No special compatibility mode is needed.
However, due to deprecation of SHA-1 code signing by Windows, if your add-in manifests are signed with SHA-1, Windows may block them. Update to SHA-256 certificates.
