I want to use lualatex and biber with the help of MiKTeX on Windows 8.1. Following is a MWE (test.bib) :

\documentclass{scrartcl}
\usepackage{fontspec}

\usepackage[backend=biber]{biblatex}
\addbibresource{test.bib}

\begin{document}

this is a test file \cite{test1}.

\end{document}

and the bibliography file (test.bib):

@BOOK{test1,
  AUTHOR = {Terrence Test},
  TITLE = {Testing is Trying and Troubling},
  YEAR = {1987},
}

I can compile test.tex just fine:

lualatex test.tex

which gives me (among others) a test.bcf file that I feed to biber:

biber test.bcf

This command prints among the correct looking INFO output a whole lot of:

Use of uninitialized value in lc at C:\Users\user\AppData\Local\Temp\par-726965686d\cache-2ee463ceb881db975cd39064dffff28a85695787\inc\lib/Biber.pm line 424.
Use of uninitialized value in string eq at C:\Users\user\AppData\Local\Temp\par-726965686d\cache-2ee463ceb881db975cd39064dffff28a85695787\inc\lib/Biber/DataModel.pm line 201.

I have deleted this folder several times but it always comes back.

The output of test.blg is:

[0] Config.pm:340> INFO - This is Biber 2.4
[1] Config.pm:343> INFO - Logfile is 'test.blg'
[48] biber-MSWIN64:287> INFO - === 
[62] Biber.pm:347> INFO - Reading 'test.bcf'

[671] bibtex.pm:1124> INFO - Decoding LaTeX character macros into UTF-8
[673] bibtex.pm:985> INFO - Found BibTeX data source 'test.bib'

and the test.bbl file is plain empty. The installed versions are:

C:\>lualatex --version
This is LuaTeX, Version beta-0.80.0 (MiKTeX 2.9 64-bit) (rev 5238)

C:\>biber --version
biber version: 2.4

and biblatex is on version 3.3 from 2016-03-09 according to MiKTeX Package Manager.

Does anyone of you nice people know what I can do so I can finally enjoy using biber on this Windows machine (please not that I do not have admin rights)? Thank you very much in advance for your help!

    An which biblatex version do you have according to your log-file? biber at least says that biblatex is too old: §found biblatex control file version 2.7, expected version 3.0" – Ulrike Fischer Mar 16 '16 at 16:12
  • Welcome to TeX.SX! Can you try deleting all auxiliary files? Biber tells us that the .bcf file it got was created by a biblatex version considerably older than v. 3.3. Maybe you have two versions of biblatex on your PC. Do an update in both User and Admin mode (see here). You can add \listfiles to the very to of your file and check the used version of the packages in the .log file. – moewe Mar 16 '16 at 16:12

    That warning means you are using incompatible versions of biber and biblatex. Your biblatex is older than your biber. See the compatibility matrix in the PDF documentation for either biblatex or biber. – PLK Mar 16 '16 at 17:18

    Thank you all very much for your prompt help. There were indeed leftovers of an old installation of MiKTeX in another directory which led biber to a wrong path. So especially the answer of @moewe put me in the right direction. – Sebastian Mar 19 '16 at 16:42

    I'm voting to close this question as off-topic because it was about a conflict caused by the remnants of another TeX distribution interfering with the path settings. The problem has been resolved by the OP (see comments above). – moewe Mar 19 '16 at 16:48
