First off, I am using TeXstudio, in case that information is important.
After searching for hours, I was so deseperate that I simply took the example from this question, tried to run it and it doesn't work. So what I have is this:
%bibtest.tex
\documentclass[a4paper,12pt]{scrartcl}
%\usepackage[style=authoryear, backend=bibtex]{biblatex} %produces errors
\usepackage[style=authoryear]{biblatex}
\usepackage{hyperref}
\addbibresource{biblio.bib}
\title{Minimal test}
\date{}
\begin{document}
\maketitle
Lorem ipsum ...\cite{Google5gram}
\printbibliography
\end{document}
%%%%%%%%%%
%biblio.bib
@ONLINE{Google5gram,
author = {Alex Franz and Thosten Brants},
organization = {Google Machine Translation Team},
url = {http://googleresearch.blogspot.com/2006/08/all-our-n-gram-are-belong-to-you.html},
title = {All Our N-Gram are Belong to You},
month = aug,
year = {2006},
}
But the resulting document has no bibliography though the text has a citation tag.
And the compiler runs multiple times, always producing the same output:
This is BibTeX, Version 0.99d (MiKTeX 2.9 64-bit)
The top-level auxiliary file: bibtest.aux
I found no \citation commands---while reading file bibtest.aux
I found no \bibdata command---while reading file bibtest.aux
I found no \bibstyle command---while reading file bibtest.aux
(There were 3 error messages)
Prozess endete mit Fehler(n)
I just don't know what I am doing wrong. I deleted all files except the two listed above, I restarted my IDE, rebooted my PC, nothing worked. I am desperate, please help!


biblatexassumesbackend=biberby default, so you need to runbiber filename, notbibtex filename. Also, in\addbibresourceyou should include the file extension, so\addbibresource{biblio.bib}. – Torbjørn T.

I would guess that the error comes from an auxiliary file, and that if you remove all of them and recompile, it would work. But should also be quite easy to tell TeXstudio to usebiber, cf. link above. – Torbjørn T. Jun 15 '16 at 14:12
