I use MiKTeX 2.9 and TexStudio 2.10.8 as my editor. And I try to use biblatex/Biber
I have installed Biber with the packackge manager of MiKTeX and configured TexStudio to use Biber.
This is the important part of my LateX file, which is about Biber:
\usepackage[style=authoryear, backend=biber]{biblatex}
\addbibresource{referenzen.bib}
So when compiling TexStudio shows me this error:
INFO - This is Biber 2.3
INFO - Logfile is '<mylatexfile>.blg'
INFO - Reading '<mylatexfile>.bcf'
WARN - Warning: Found biblatex control file version 2.6, expected version 2.9

I noticed the warning about the biblatex control file and therefore I looked in the package manager MiKTeX what's the version of biblatex:
And surprisingly it is called v2.9 and not 2.6 there.
So to verify this version error I looked into my .bcf
file and it indeed is labeled v2.6 there:
<?xml version="1.0" encoding="UTF-8"?>
<bcf:controlfile version="2.6" xmlns:bcf="https://sourceforge.net/projects/biblatex">
<!-- BIBER OPTIONS -->
[...]
So why is there this version discrepancy and how can I get it to compile correctly?
biblatex
does not coincide with thebiblatex control file
version. (The version numbers of these two are stepped up independently.) It is just coincidence that Biber 2.3 asks for bcf version 2.9 and you havebiblatex
2.9a installed. Both the Biber andbiblatex
manual feature a compatibility matrix stating that Biber 2.3 can only be used together with version 3.2 ofbiblatex
. See also the section Make Sure Versions of Biber andbiblatex
Match in Troubleshooting for biber.
