3) Download & install (step-by-step)

1. Go to ArKaos support/download page and choose the product: MediaMaster 5.x or GrandVJ.
2. Select the correct OS installer (Windows .exe/.msi or macOS .dmg/.pkg) and download.
3. On Windows: run the installer as Administrator; follow prompts; accept drivers if asked.
4. On macOS: open the .dmg, drag app to Applications (or run the .pkg installer); allow any kernel extensions or drivers in System Preferences if required.
5. After install, open the application and confirm the Documentation/Release Notes folder is present in the application folder.

Error 2: "License expired or invalid"

• Cause: System date changed or hardware ID changed.
• Fix: Do not change RAM or GPU after licensing. If error persists, open regedit, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Arcaos, delete the License folder, and re-import the license.

6) Basic workflow (MediaMaster / GrandVJ concepts)

• Library: import visuals (videos, images, sequences). Supported formats: common codecs (H.264/HEVC may require OS codec support); prefer uncompressed or ProRes for performance-critical shows.
• Cues/Slots: drag visuals into slots/pagers to build cue lists or live decks.
• Layers/Channels: create layers and assign visuals to channels; set blend modes and opacity.
• Effects: apply built-in effects and transitions; chain effects and tweak parameters in real time.
• Mapping: use the built-in video mapper to place visuals on arbitrary outputs (projectors, LED panels). For complex rigs, use advanced geometric correction and soft-edge.
• DMX/Pixel mapping: map outputs to DMX or pixel mapping modules for LED panels (use LED Mapper workflow).

ArcaOS 5.1 (codenamed "Blue Lion") is a significant milestone because it was the first version to introduce widespread support for UEFI booting. This allows the operating system to be installed on modern hardware that no longer supports legacy BIOS, bridging the gap between 1990s software architecture and 2020s hardware.
