{"answer":"Recommended action: Install/modify VS or Build Tools adding 'Desktop development with C++' (on WoA add 'Visual C++ compilers and libraries for ARM64' and ATL for ARM64); optionally `Install-Module VSSetup -Scope CurrentUser`; unset stale msvs_version; also check whether a newer package version ships prebuilds so no compile is needed.\n\nOption: Add the C++ workload [evidence: official_recommended_action]\nApplies when: See record scope.\nSteps:\n1. Visual Studio Installer → Modify → 'Desktop development with C++' (MSVC toolset + Windows SDK)\n2. Or: choco install visualstudio2026-workload-vctools -y\n3.
