I installed biber through MiKTeX's package manager but when trying to compile my references, nothing happens, as if biber was not installed when, in fact, its .exe is present under C:\Program Files (x86)\MiKTeX 2.9\miktex\bin and this path is included in the system variables. Bibtex works just fine.
I tried to delete the par-4e69636f6c6173 folder under C:\Users\Nicolas\AppData\Local\Temp created each time I try to run biber through the command prompt, but to no avail. Typing biber test systematically creates 4 files in my Temp folder: biber.exe, libgcc_s_sjlj-1.dll, libstdc++-6.dll and perl516.dll.
I also tried to run "Refresh FNDB" in MiKTeX settings.
Any insights ?
Here is a MWE
\documentclass{article}
\usepackage{fontspec}
\usepackage{filecontents}
\usepackage{csquotes}
\usepackage[style=apa]{biblatex}
\addbibresource{refs.bib}
\begin{filecontents}{refs.bib}

\end{filecontents}

Commands executed:
xelatex test produces test.log/aux/bcf/pdf, refs.bib and test.run.xml.
biber test or biber test.bcf produces nothing:

biber --versionat the command line? What happens if you try to compile a document via the command line (pdlfatex testbiber testpdlfatex testpdlfatex test)? – moewe Nov 16 '13 at 08:10MiKTeX-BibTeX 2.9 4360 (0.99d)). PDFLaTeX works fine too. Changing Bib(la)tex's defautlt field in Texmaker (bibtex %) to"C:/Program Files (x86)/MiKTeX 2.9/miktex/bin/biber.exe" %does not work either. – Nicolas M Nov 16 '13 at 09:22myfile.bcf, try type in your command linebiber myfile.bcf. Maybe you can see that in you project folder ismyfile.bblwhich has size 0B. This is important. In command line, you can se warning:INFO - This is Biber 1.8INFO - Logfile is 'myfile.blg' INFO - Reading 'myfile.bcf'WARN - Warning: Found biblatex control file version 2.4, expected version 2.5 and this problem. Is that so? – JardaFait Nov 16 '13 at 10:02test.bblfile, onlytest.auxandtest.bcf. I added more informations into my question. – Nicolas M Nov 16 '13 at 12:49http://www.ctan.org/tex-archive/biblio/biber/binaries/Windowsorhttp://sourceforge.net/projects/biblatex-biber/?source=directorydid not change anything. – Nicolas M Nov 16 '13 at 13:38C:\Users\Nicolas\AppData\Local\Tempdirectory and subdirectories. I lowered the User Account Control setting to the minimum and now it works. I had another issue with Foxit Reader Updater.exe not being able to run and this error messagewindows cannot access the specified device...and now it's solved too, probably for the same reason has this .exe was also inTempdirectory. – Nicolas M Nov 16 '13 at 23:15
