v1.5.3 — Existing Build Tools installer fix

Fixes a confirmed cause of Microsoft component setup exit code 1: Visual Studio Build Tools 2022 was already installed, but our component setup attempted a fresh installation.

• Discover an existing Build Tools 2022 instance even when required C++ components are missing.
• Add required components with modify, using that instance's exact installation path and channel, instead of attempting a duplicate installation.
• Apply the corrected command selection in both the installer and the updated updater. Keep fresh installation available when no instance exists.
• Quote paths containing spaces, preserve the existing channel (including LTSC), and reject malformed arguments.
• Show the failed prerequisite check in setup logs and provide a clearer manual Update/Modify workaround.

If your installation previously failed

Download the new Install-Table-Tennis.exe from this release and run it again. You can keep your existing Build Tools installation and game files.

If Build Tools is outdated, open Visual Studio Installer, update Build Tools 2022, then select Modify and add Desktop development with C++, the Windows SDK, C++ Clang Compiler for Windows and C++ CMake tools for Windows. Retry the game installer afterwards.

Users whose existing build tools already work can use the built-in updater. An older installed updater still has its older component setup code, so users blocked specifically at component installation should use the new standalone installer.

Validation and scope

All 10 updater client regression tests pass, including compiled production/test .NET updaters, syntax-checked PowerShell 5.1 command planning, fresh/existing-install selection, path quoting, channel preservation, invalid argument rejection and read-only discovery. No actual Microsoft component installation or modification was performed during these tests, and the affected user's full installation has not yet been retested.

The matched game engine and gameplay code are unchanged from v1.5.2. Its ultrawide menu fix and independent picture-aspect options remain included. Experimental high-refresh work and native 1080p/4K menu work are not included; gameplay remains paced at 60 FPS.
