After updating MikTeX today, I get the error
graphics.sty - line 100 - File 'pdftex.def' not found
I've reduced the document to the following and still get the error.
\documentclass[10pt, a4paper]{article}
\usepackage{tikz}
\begin{document}
\end{document}
I've found the missing document here (as part of a bundle): pdftex.def. But I have no idea, where to put the pdftex.def file or what else I could do to resolve this error.
I work on Win 10, with MikTeX 2.9, TeXstudio 2.11.0.
Thanks for any help!
