Biblatex & Biber in TexStudio on Windows - Central Bibliography [closed]

Question

Introduction

I have a TeX file that contains a number of references built using TeXStudio on Windows 10 using TeXLive as a backend. Since migrating from BibTeX to BibLaTeX/Biber I haven't been able to access my centralized library.bib file located in $TEXMFLOCAL.

I previously used standard BibTeX to retireve references stored in a centralized/database bibliography created by Mendeley in the BibTeX format. This library is located at $TEXMFLOCAL/bibtex/bib/local/library.bib (which translates to D:\Dev\texlive\texmf-local\bibtex\bib\local\library.bib on my system)

Current Software

• Mendeley 1.16
• TeXLive 2015
• TeXStudio 2.10.8

Compile Sequence

pdfLatex -> BibTeX/Biber (as appropriate) -> pdfLatex -> pdfLatex

Whilst debugging this problem, I have also been clearing the auxiliary files and compiling from scratch to eliminate any potential issues with corrupt files.

BibTeX MWE

With BibTeX, I can access this library using:

\documentclass[10pt,a4paper,final]{article}
\usepackage{lipsum} % just for MWE

\begin{document}
  \section{Some Title}
    \lipsum[2]
  \section{Another Title}
    \lipsum[2]
    \par Summarised point \cite{TheRef2016}
  \bibliographystyle{unsrt}
  \bibliography{library}
\end{document}

BibLaTeX MWE (BibTeX Backend)

This example functions as inteded by still uses BibTeX as the backend.

\documentclass{article}
\usepackage{lipsum} % just for MWE
\usepackage[backend=bibtex]{biblatex}
\addbibresource{library.bib}

\begin{document}
  \section{Some Title}
    \lipsum[2]
  \section{Another Title}
    \lipsum[2]
    \par Some text here \cite{TheRef2016}
  \printbibliography
\end{document}

BibLaTeX MWE (Biber backend)

A .bib file located in the same directory works fine as demonstrated by the MWE on the wiki (MWEB (for BibLaTeX) - Tex.SE Wiki).

However, adjusting it to use the centralized bibliography as before results in an error message saying that the bibliography file cannot be found.

\documentclass{article}
\usepackage{lipsum} % just for MWE
\usepackage[backend=biber]{biblatex}
\addbibresource{library.bib} % Also tried with \bibliography{library.bib}

\begin{document}
  \section{Some Title}
    \lipsum[2]
  \section{Another Title}
    \lipsum[2]
    \par Some reference \cite{TheRef2016}
  \printbibliography
\end{document}

These are the error messages given when compiling with Biber:

INFO - Looking for bibtex format file 'library.bib' for section 0
ERROR - Cannot find 'library.bib'!

Conclusion

I'm probably missing something fundamental but have been stumped by this problem for the past couple of hours with no luck in finding a solution.

Thanks in advance.
