Description

Bug fix. Adds the v143 (MSVC 14.44 / VS 17.14) ARM64 toolset component to windows-2025-vs2026.

The pinned v143 toolset was installed only in the x86/x64 flavor (VC.14.44.17.14.x86.x64), while the native windows-11-vs2026-arm image also ships the ARM64 flavor (VC.14.44.17.14.ARM64). As a result, ARM64 builds with PlatformToolset v143 failed on windows-2025-vs2026. This adds the missing ARM64 component so cross-compilation matches the ARM image.

Install Microsoft.VisualStudio.Component.VC.14.44.17.14.ARM64 so the
pinned v143 (MSVC 14.44 / VS 17.14) toolset supports ARM64 targets,
matching windows-11-vs2026-arm. Previously only the x86.x64 flavor was
present, so ARM64 builds with PlatformToolset v143 failed.

Pull request overview

This pull request fixes ARM64 cross-compilation failures on the windows-2025-vs2026 runner image by aligning the installed v143 (MSVC 14.44 / VS 17.14) toolset components with what’s available on the native windows-11-vs2026-arm64 image.

Changes:

  • Add the missing Visual Studio component Microsoft.VisualStudio.Component.VC.14.44.17.14.ARM64 to the windows-2025-vs2026 toolset component list so PlatformToolset=v143 ARM64 builds can succeed.
