I seem to be getting a strange error after updating MiKTeX 2.9. I am using pdfLaTeX and TeXmaker with the graphicx package to include .png images. When I try to compile, I get the error LaTeX Error: File 'title' not found. If I include the file extension, then the error becomes LaTeX Error: Cannot determine size of graphic in title.png (no BoundingBox). I wasn't getting these errors a few days ago when I started creating my presentation. It has also worked without problems in the past.



Also, from the logfile it seems that pdfLaTeX is not in PDF mode, and that all graphics are being treated as .eps:

Package: ifpdf 2011/01/30 v2.3 Provides the ifpdf switch (HO)
Package ifpdf Info: pdfTeX in PDF mode is not detected.
File: title.png Graphic file (type eps)

Does anyone know how to fix this problem?

    Welcome to TeX.sx! The first problem is related to the second (and actual) problem. latex cannot determine the natural dimensions of an image. So the real question is: Why is pdfLaTeX not in PDF mode? Does your MWE compile if you use pdflatex from the command line (pdflatex <filename>)? It seems as if your editor is set up to use latex rather than pdflatex. Commented Feb 18, 2013 at 5:17

    Could it be that you have several files with basename title, that some of them have a pdf or an eps extension and that they're corrupt? If yes, a possible solution may be adding the extension to the filename title.

    @m0nk3y: There was an update some days ago (12.2.) which broke the formats. The error has been corrected but perhaps you still have remains. Run the update manager (admin + user mode). Recreate all formats. If the problem persist you will have to find the local ini-files and correct them manually. If you are in a hurry: you can also put \pdfoutput=1 at the start of your document, this will switch the mode back to pdf. Commented Feb 18, 2013 at 8:22

    @hjschulz: Updating is not enough. You should also recreate the formats (as user). If this doesn't help: Rename in the UserData and (perhaps) CommonData-root (not in the main root!) in the folder miktex/config formats.ini, language.ini and if it exists pdflatex.ini. And then recreate the formats again. (This can change the language and format settings, you can reset them in miktex->settings). Commented Feb 18, 2013 at 14:30

    @m0nk3y: I explicitly wrote that you should not change files in the main root (=installation root). Go to miktex-setting, tab "root", activate "show miktex roots", it will show you the path to UserConfig (not UserData as I wrote by mistake in the previous comment). There you will find the local ini's. Commented Feb 19, 2013 at 8:35

This problem was solved by renaming pdflatex.fmt and pdftex.fmt in the CommonConfig/miktex/data/le/pdftex directory and then recreating formats as "user".
