I am having a common problem of incompatible packages, but I have not found anyone having the same problem.
I am trying to use {multibib} package with biblatex:
\usepackage{multibib}
\usepackage[backend=bibtex]{biblatex}
\addbibresource{references,referencesSoftwares,referencesBooks}
But it returns:
Package biblatex Error: Incompatible package 'multibib' \begin{document}
- I have to use biblatex.

Im suspecting that you would like different sections for references, Software and books. \printbibliography excepts optional arguments, please also refer to section 3.7.2 The Bibliography of the biblatex manual
So for your use case I would expect it to be like in this answer
