I am new to LaTeX and am writing my thesis in TexMaker and MiKTeX. I am having an issue with incompatible biber and biblatex versions. I have gone through several other threads here and am pretty sure TexMaker is configured to compile correctly. The error I get is

Error: Found biblatex control file version 3.4, expected version 3.3. This means that your biber (2.7) and biblatex (3.11) versions are incompatible. See compat matrix in biblatex or biber PDF documentation. INFO - ERRORS: 1

even on simple examples. I have checked MiKTeX program manager for the versions of biber v2.11 and biblatex v3.11. They seem to be compatible according to the biblatex documentation. However, these are not the versions TexMaker displays in the error message. I have checked the version of biber in the command prompt and it says biber v2.7. I'm really not sure how to proceed at this point.

Another conflicting issue is in the MiKTeX program manager, when looking at the version of biber installed. When searching for biber, the Name displayed is miktex-biber-bin-x64, Packaged on 2018-03-06, Installed on 2017-07-10. I don't know if this means the latest version was never really installed. The LaTeX program manager gives me no option to update it.

    Check the log file, you might have a stray version laying around somewhere. – Johannes_B Mar 28 '18 at 5:17
  • @Johannes_B I'm don't know how to check that. – Alan Mar 28 '18 at 5:35
  • What do you get if you type where biber in the command line? Did you do your updates in both User and Admin mode? If you installed MikTeX as Admin there are two levels at which packages are installed: System-wide with Admin privileges and for you only as User. If Biber was installed as Admin you will need to run the Updater as Admin to update Biber. The fact that you can't update Biber in the Package Manager makes me think you are using the User Package Manager. So open the Package Manager (Admin) and try to update the Biber binary. – moewe Mar 28 '18 at 6:04
  • I installed with the single user option. When I try to run Admin versions they just throw an error saying I am a single user version. I manually downloaded biber v2.11 and moved that file into the miktex folder and now I do not have the version incompatibility error anymore. Now I get warnings on Empty bibliography and Please (re)run Biber on the file:(...) and rerun LaTex afterwards. I'm not sure if this needs to become a new question at this point. – Alan Mar 28 '18 at 6:11

    I'm voting to close this question as off-topic because it is about a version incompatibility between biblatex and Biber that is solved by updating. – moewe Apr 5 '18 at 6:30
