I recently had to reinstall Windows 10. Upon doing so, my Miktex and Texmaker were deleted and needed to be reinstalled as well. I have been learning LaTeX via Texmaker since July of this year.

After I had reinstalled Texmaker and Miktex, I went to run my dissertation document. I use BibLatex and Biber for the references. When I run the document, the following error message appears below:

INFO - This is Biber 2.7 INFO - Logfile is 'Dissertation Master File.blg' INFO - Reading 'Dissertation Master File.bcf' ERROR - Error: Found biblatex control file version 3.4, expected version 3.3. This means that your biber (2.7) and biblatex (3.8a) versions are incompatible. See compat matrix in biblatex or biber PDF documentation. INFO - ERRORS: 1

My questions are, has anyone ran into this problem before and how do I fix it? Please feel free to inform me of anything you need from my end as this is my first question asked and I am a novice.

    miktex-biber was updated to version 2.8 a week ago. – Bernard Nov 20 '17 at 21:25

    If you're using version 3.8a (2017/11/05) of biblatex, you must use version 2.8 of biber. Your installed version, 2.7, isn't sufficiently up to date. – Mico Nov 20 '17 at 21:27

    Thank you very much for that. How do I go about installing version 2.8? I've updated everything through Miktex (admin and user) but it still doesn't work. – Chris Felts Nov 20 '17 at 23:20

    I'm voting to close this question as off-topic because it is about a clearly stated version incompatibility that was solved by updating the packages involved. – moewe Nov 29 '17 at 15:03
