Introduction

Q4: Why does the installer say "Microsoft Office 2010 is required"? You may see this warning when PIAs are being installed. Ignore it—the runtime itself will work with newer Office versions. You can suppress the warning by using the /quiet flag.

Part 7: Frequently Asked Questions (x64 Specific)

Q1: Can I install both x86 and x64 VSTO runtimes side-by-side? Yes, but it is not recommended. The x64 installer places files in Program Files and 64-bit registry; the x86 installer uses Program Files (x86) and the WOW6432Node registry. However, if you have both, Windows will attempt to load the appropriate version based on the calling process (Office x86 uses x86 runtime; Office x64 uses x64 runtime). This works in theory, but causes clutter and occasional loader conflicts.
