Documentation / Install guides

Install Windows C/C++

The engine as a DLL, with the header and both bitnesses.

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-cpp.zip.

Download windows-cpp

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-cpp.zip
cl /I include your_app.c win64\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"

int main(void) {
    void *pdf = pdfCreatePDF("hello.pdf");
    pdfAppend(pdf);
    pdfSetFont(pdf, "Helvetica", fsNone, 24.0, 1, cp1252);
    pdfWriteFText(pdf, taCenter, "Hello from LumasPDF");
    pdfEndPage(pdf);
    pdfCloseFile(pdf);
    pdfDeletePDF(pdf);
    return 0;
}
