v1.2.2 — Windows 11 compatibility

What's included

• Transactional installer publication with rollback protection.
• Hash-verified x86 Wlbrw32.dll replacement before shortcuts are created.
• Pester unit tests for installer staging, rollback, INI updates, path mapping, and shim verification.
• Node.js unit tests for archive URL normalization, rewriting, and network-target blocking.
• GitHub Actions CI that runs tests, builds the native shim, builds the Windows installer, and publishes tagged release assets.

The original 3DATLAS CD must be mounted during installation and while running the program.

v1.2.1 — Transactional installer

Fixed

• The installer now stages the runtime, converted media, and offline archive before publishing them.
• The Windows 11 Wlbrw32.dll replacement is hash-verified before shortcuts are created.
• Failed retries roll back instead of leaving an older configuration beside the original 1998 DLL.
• Added installer-side validation for the DLL hash sidecar.

The original 3DATLAS CD must be mounted during installation and while running the program.

v1.1.1 — Archive Mode launch fix

Archive Mode launch fix

The previous symptoms were caused by launching the untouched original Program Files copy rather than the user-local Windows 11 Archive Mode runtime. This release makes the correct path harder to miss:

• Adds a clearly named desktop shortcut: Compton's 3D World Atlas Deluxe - Windows 11 Archive Mode.
• Keeps the Windows 11 Start Menu shortcuts and documents that the original shortcut must not be used.
• Adds a launcher watchdog fix that brings legacy modal dialogs above the Atlas main window so they can be dismissed.
• The local WonderLink shim continues routing Online commands to the offline archive; no retired live URLs are opened.

Use the installer-created Windows 11 shortcut. The original Program Files installation remains untouched by design.

Verify SHA256SUMS.txt before running the installer.

v1.1.0 — Faster, quiet installer

Faster, quiet Windows 11 installer

This release fixes the slow and noisy installation experience:

• Archive downloads use 20 bounded parallel workers and retry throttled files with a smaller pool.
• AVI sources are staged locally and converted/validated with four parallel workers.
• A complete existing offline archive mirror is reused on subsequent runs.
• PowerShell and worker processes run hidden behind the installer progress UI; no separate console window is opened.
• The installer records detailed compatibility-phase diagnostics in Install-AtlasWindows11.log.
• The installer automatically finds the physical disc on another drive letter when /DISC is omitted.

The installer still requires a lawful physical 3DATLAS CD and Internet access for a first-time archive mirror download. It contains no commercial Atlas executable, CD data, converted media, or generated archive snapshot.

Verify SHA256SUMS.txt before running the installer.

v1.0.0 — Tested Windows 11 installer

Compton's 3D World Atlas Deluxe — Windows 11 compatibility

This release contains the tested user-scoped Windows installer and its SHA-256 checksum.

Requirements

• A lawful physical Compton's 3D World Atlas Deluxe CD mounted as volume 3DATLAS (default drive D:).
• Internet access during installation for the separate LGPL FFmpeg/Node.js tools and the Internet Archive static Online documentation mirror.
• Windows 11.

The installer does not include the commercial Atlas executable, CD data, converted movies, or generated archive mirror. It refuses to continue without the physical disc and leaves the original disc/Program Files installation untouched.

Verify SHA256SUMS.txt before running the installer. See the repository README for the complete archive coverage and troubleshooting guide.
