Install Windows on ARM64

A native ARM64 build of the engine for Windows.

1. Get the package

The download is public and needs no key — unlicensed output carries an evaluation watermark and nothing else is restricted. The package file is windows-arm64.zip.

Download windows-arm64

2. Check your platform

Two separate facts per platform: whether a licence key for this package covers it, and whether the download ships an engine binary for it.

3. Install

unzip windows-arm64.zip
cl /I . your_app.c LumasPdf.lib

4. Licence it

A licence is one key string, set once at startup. Buying one and installing it is covered by how licensing works; until then the engine runs fully functional with an evaluation watermark.

5. Your first PDF

The smallest complete program: create, write, close.

#include "lumaspdf.h"
/* identical to the x64 build -- same 1,649 exports */
