System requirements
MiniBook3 is offline-first. Cloud is optional for licence, payments, and Enterprise — never the lunch rush.
| Aspect | Minimum | Recommended |
|---|---|---|
| Operating system | Windows 10 (64-bit) · Ubuntu 22.04 LTS or equivalent Linux | Windows 11 · Ubuntu 24.04 LTS / current Fedora or Debian stable |
| Memory (RAM) | 4 GB | 8 GB or more for large catalogs and concurrent shifts |
| Disk space | ~400 MB for the app + room for your ledger | 2 GB+ free; SSD preferred for large Solo catalogs |
| Display | 1280 × 720 | 1920 × 1080 or higher |
| Network | Offline-first — sales work without internet | Optional online for licence activation, payments, and Enterprise sync |
| Linux extras | Wayland or X11; fuse2 for AppImage on some distros | Dedicated install root under ~/Applications or /opt for path-safe updates |
Verify & trust
One SHA256SUMS.txt per release covers every platform binary. Prefer the SHA-256 on each download row when present, or verify with the commands below.
Windows (PowerShell)
Hash a single file and compare to the row SHA-256 or the matching line in SHA256SUMS.txt:
Get-FileHash .\<downloaded-file> -Algorithm SHA256Answered questions
Edge cases that break installs — answered before they break yours.
Which Linux option should I pick?
Use the one-line install on a normal online desktop (Copy the curl command). Prefer the tarball when the shop is air-gapped. Use the .deb on Debian/Ubuntu if you want package management. AppImage is for trials and USB demos.
Where is the Windows portable zip?
When a portable zip is published on the release, it appears in the Windows table. Until then, use the installer or the one-line PowerShell command — both create a dedicated install root that updates can safely replace.
How do I verify the download?
Prefer the SHA-256 on each download row when Admin filled it in. Or download the single release SHA256SUMS.txt from Verify & trust (one file covers every platform binary), then run the copyable verify command for your OS.
Will updating wipe my shop data?
No — the ledger lives outside the app bundle (~/.local/share/MiniBook3/ or %LOCALAPPDATA%\MiniBook3\). Install into a dedicated MiniBook3 folder so path-safe updates can apply.
