I've imported a tex file that works splendid on Mac OS X with TeXShop to TeXworks on a Windows XP machine (using the latest MiKTeX version). In it, I use the following commands \usepackage[backend=biber]{biblatex} and \addbibresource{MyLibrary.bib}.
However, when I run XeLaTeX I get the following error every time
Package biblatex Warning: Please (re)run Biber on the file
I've seen a lot of threads about this, but no specific solution.
biblatex. However, we'll need an example to offer more guidance. – Joseph Wright♦ Sep 15 '12 at 13:31
