I get this error:
Package biblatex Info: ... file 'authoryear-icomp.cbx' found.
(authoryear-icomp.cbx.tex
File: authoryear-icomp.cbx 2016/09/17 v3.6 biblatex citation style (PK/JW/AB)
! Package keyval Error: No value specified for labeldate.
See the keyval package documentation for explanation.
Type H <return> for immediate help.
...
l.5 ... pagetracker,sortcites,autocite=inline}
Try typing <return> to proceed.
If that doesn't work, type X <return> to quit.
the line of authoryear-icomp.cbx.tex that gives the error is:
\ExecuteBibliographyOptions{labeldate,uniquename,uniquelist,ibidtracker=constrict,
pagetracker,sortcites,autocite=inline}
Here is the MWE (some days ago it worked, I've updated packages with MiKTeX 2.9 today):
\documentclass[11pt,openright]{book}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage[british]{babel}
% biblatex
\usepackage[style=authoryear-icomp, natbib=true, maxcitenames=2, maxbibnames=11, backend=biber, hyperref=true, pagetracker=page]{biblatex}
\usepackage{csquotes}
% package hyperref
\usepackage[unicode=true,pdfusetitle,
bookmarks=true,bookmarksnumbered=false,bookmarksopen=false,

Deinstalling the arabi package probably doesn't help, since then MiKTeX searches on and might find some otherbblopts.cfgfile. – gernot Sep 19 '16 at 22:47bblopts.cfgunderC:\Users\myuser\AppData\Local\Programs\MiKTeX 2.9\tex\latex\arabi, the row bblopts.cfg 2005/09/08 v0.1 add Arabic and Farsi to "declared" options of babelnow is onlybblopts.cfg` but the error is still present :'( – CarLaTeX Sep 20 '16 at 06:20authoryear-icomp.cbxis not the 3.6 version: In 3.6 the line you quote should be\ExecuteBibliographyOptions{labeldateparts,uniquename,uniquelist,ibidtracker=constrict, pagetracker,sortcites,autocite=inline}(note that thelabeldateoption that causes you trouble has been renamedlabeldateparts). – moewe Sep 20 '16 at 07:28authoryear-icomp.cbx.texflying around. Where is it, where does it come from? And why is it there? You should probably just get rid of it, so you get the goodauthoryear-icomp.cbxonly. – moewe Sep 20 '16 at 07:30.cbxfiles! You seem to have a file that is calledauthoryear-icomp.cbx.texwith an additional.texat the end, find that file and tell us where it is. (If you have remnants of an old installation of MikTeX, you should make sure to get rid of them for good, they can cause all sorts of trouble.) – moewe Sep 20 '16 at 07:36authoryear-icomp.cbx.texin your current document folder. Probably you saved it there sometime ago by accident. Remove this local file. – Ulrike Fischer Sep 20 '16 at 07:38labeldatehas been renamed tolabeldateparts. It is very unlikely that someone with the same symptoms will have had the same cause. – moewe Sep 20 '16 at 15:39
