I am looking for a freeware to convert Microsoft Word (.docx or .doc) to PDF.
It would be nice to use this without installation.
I would like it to run on Windows and do not want any online converters - it must be on my computer.
You are looking for an open source converter which converts Microsoft Word (.docx or .doc) to PDF, and then I found Office To PDF utility that help you to convert you DOCX file into PDF. OfficeToPDF is a command line utility that converts Microsoft Office 2003, 2007, 2010 and 2013 documents from their native format into PDF using Office's in-built PDF export features.

NW Docx Converter (formerly Docx2Rtf) is a feature-rich file conversion and PDF tool set.It's free and As the name implies, it can convert Word 2007 DOCX/DOTX to RTF or PDF format without installing Word. However, Docx2Rtf has many more features including the ability to open, modify, view, print, and convert to PDF from many file types including LibreOffice SXW/ODT, HTML, RTF, Palm, PhotoShop, TIFF, PDF, and many more. Can rearrange and delete PDF file pages.

on windows i use the FLOSS-software PDFCreator.
you don't have to learn how to convert a file, because it acts like a normal printer and so you can generate PDF-, PNG-, JPEG-, SVG-, TIFF-, PS-files and much more from every program with a print-function.
BUT, you guess right, you have to install it!
