Note

GroupDocs.Viewer for Python via .NET ships as a self-contained wheel that bundles the .NET runtime it needs. No Microsoft Office, Adobe Acrobat, or Mono install is required.

• Windows 10 (x64, x86)
• Windows 11 (x64)
• Windows Server 2016 and later (x64)

• Any modern x86-64 distribution that can install the manylinux1 wheel — Ubuntu 20.04+, Debian 11+, RHEL 8+, and equivalents.

• macOS 11 (Big Sur) and later.
• Both Intel (x86_64) and Apple Silicon (arm64 / M-series) are supported.

GroupDocs.Viewer for Python via .NET supports every Python release from 3.5 through 3.14.

Download Python from the official website.

The library is distributed on PyPI under the name groupdocs-viewer-net and ships as four platform-specific wheels per release:

pip automatically picks the right wheel for your platform.

GroupDocs.Viewer uses System.Drawing.Common for image rendering, which on Linux needs a few system packages. Install them with apt, dnf, or the equivalent for your distribution:

# Debian / Ubuntu
sudo apt install libgdiplus libfontconfig1 ttf-mscorefonts-installer
sudo fc-cache -f

# Fedora / RHEL / Rocky
sudo dnf install libgdiplus fontconfig

libgdiplus provides the GDI+-compatible API used by the rendering engine. ttf-mscorefonts-installer (Debian / Ubuntu) supplies the core Microsoft TrueType fonts required to render Word / Excel / PowerPoint documents faithfully.

If your distribution’s ICU or OpenSSL versions differ from what the bundled runtime expects, install both and point the runtime at them — no exact version is required.

brew install mono-libgdiplus

If you see a DllNotFoundException: libSkiaSharp error, a stale system copy is shadowing the bundled library. Rename it out of the way:

sudo mv /usr/local/lib/libSkiaSharp.dylib /usr/local/lib/libSkiaSharp.dylib.bak

No additional system libraries are required.
