This question already has an answer here:

Im trying to run my file and I keep getting the error:

ERROR - Error: Found biblatex control file version 3.4, expected version 3.3. This means that your biber (2.7) and biblatex (3.9) versions are incompatible. See compat matrix in biblatex or biber PDF documentation.

I already tried downloading Biber from here https://sourceforge.net/projects/biblatex-biber/?source=typ_redirect I then put the biber file next to my tex document and it still gives the same error message.

I searched for Biber in the package manager and could not find it. How can I update my Biber to 2.9?

After trying to select all to update, the process won't work.

    I recently had the same problem under MikTeX. Updating all packages using the MiKTeX Package Manager solved the problem for me. – hbaderts Dec 15 '17 at 14:41
  • Im on MiKTeX windows-64. I just reinstalled MiKTeX, updated the packages, and it still says that I have biber 2.7 – Michael Dec 15 '17 at 15:37
