I'm using miktex portable with the included TeXworks editor. I need to compile a document using:
pdfLaTex - Biber - pdfLaTex
If I run the three commands individually, they work fine. However, when I create a new tool to run all 3 together, the Biber part seems to get skipped, I cannot find any information about Biber in the console output.
Also, I've noticed that when I run pdfLaTex by itself, it creates an aux and bcf file, but when I run all 3 together, those files are not created. I know Biber needs the bcf file to run, so I suspect this may be part of the problem, though I don't know what is causing it.
This is the confuguration I have for the tool that I created in TeXworks:
Running the three programs individually works, but it would be nice if all 3 could run together. Any ideas of what could be wrong here?

latexmkorararainstead. I think if you want to use Biber withtexifyyou need to change some environment variables. – moewe Nov 02 '16 at 23:10
