System requirements
Docuflair Desktop runs on Windows 10/11 (64-bit) and macOS 12 or later. The installation package brings every component with it — the runtime, text recognition (OCR) with 18 language packs, detection data and an embedded browser for HTML and email files. Nothing has to be pre-installed on the target machine (no .NET, no Microsoft Office, no PDF driver).
Windows
Section titled “Windows”| Minimum | Recommended | |
|---|---|---|
| Operating system | Windows 10 (64-bit), version 21H2 | Windows 11, current feature update |
| Architecture | x64 — 32-bit Windows and Windows on ARM are not supported | x64 |
| Processor | 4 cores (Core i3 / Ryzen 3 from around 2020) | 8 cores or more with high single-core performance (Core i7/i9, Ryzen 7/9 from around 2022) |
| Memory | 8 GB | 16 GB (32 GB for very large scan batches) |
| Disk | 2 GB free | SSD/NVMe, 5 GB free |
| Display | 1366 × 768 | 1920 × 1080 or higher (scaling up to 200%) |
| Scanner (optional) | TWAIN scanner with a 64-bit driver | — |
| Installation | Administrator rights for the setup | — |
| Minimum | Recommended | |
|---|---|---|
| Operating system | macOS 12 (Monterey) | current macOS |
| Architecture | Apple silicon (arm64) or Intel (x64) — separate native packages, no emulation | Apple silicon (M series) |
| Processor | Intel Mac from around 2018 (4 cores) | Apple M1 Pro or later |
| Memory | 8 GB | 16 GB |
| Disk | 2 GB free | 5 GB free |
| Display | — | Retina is supported natively |
| Scanner (optional) | Any scanner supported by macOS (USB or network) | — |
On first start a Gatekeeper prompt may appear (the package is not notarised): confirm the app once in the Applications folder by right-clicking and choosing Open. For scanning over network devices, macOS asks once for permission to search the local network.
Disk space
Section titled “Disk space”| Item | Size (approx.) |
|---|---|
| Installation package (download) | 280 MB |
| Installed application | 900 MB — of which 430 MB browser, 85 MB OCR languages, 22 MB detection data |
| User data (settings, dictionaries, pseudonym mappings) | a few MB, grows with use |
Case files (.dfr) |
a few MB; for scanned cases the image data is held in the file (1–5 MB per page) |
Network
Section titled “Network”Network access occurs in three situations only:
- once for licence activation (
license.administrator.at, HTTPS/443), - optionally for the AI assistant (the API of the provider you choose),
- optionally when sending from the scan tool to a Docuflair server.
All connections can be routed through a proxy. In isolated networks it is enough to permit activation once; without an API key configured, the AI assistant stays inactive.
Planning notes
Section titled “Planning notes”- One instance per machine — across all sessions. On terminal servers the desktop application is therefore not suitable for multi-user operation; the server solution Docuflair Redact & Mask covers that case.
- Choose OCR languages sparingly: each additional language slows recognition down and can reduce accuracy (Settings → Text recognition; the default is the interface language plus English). As a rule of thumb on recommended hardware: a few seconds per page.
- No graphics card needed — text recognition uses the CPU exclusively. During recognition several 300 dpi page images are held in memory at the same time (around 35 MB per A4 page and thread).
- Where to store files:
.dfrfiles work on network drives but are slower. On notebooks, run large batches on mains power — in power-saving mode the operating system throttles the CPU. - Endpoint protection: with very restrictive policies, add an exception for the program folder; parallel rasterisation briefly generates a lot of file and memory activity.
