After updating packages this morning nothing works anymore (I am working under Windows 8). Particularly, compiling files with TeXWorks returns the message:

running 'initexmf --quiet --update-fndb' to refresh the file name database The operation failed for some reason.

This is of little help, unfortunately. I tried updating FNDB manually with no change.

  • We need a bit more information. For example which latex installation do you use?

  • I use PDFLaTeX. The full erroe message in the consol is: "You may want to visit the MiKTeX project page (miktex.org), if you need help. Sorry, but C:\Program Files (x86)\MiKTeX 2.9\miktex\bin\miktex-pdftex.exe did not succeed. The log file hopefully contains the information to get MiKTeX going again: C:/Users/cassese/AppData/Local/MiKTeX/2.9/miktex/log/miktex-pdftex.log You may want to visit the MiKTeX project page (miktex.org), if you need help."

  • And what does the log that is referred to say?

    Start the package manager (admin and then user version). Click on "repositories -> synchronize". Then search for new packages starting with miktex and install them. Then try again to create the fndb and the formats. Sep 2, 2015 at 8:37

    I'm voting to close this question as off-topic because it was resolved in comments ages ago.

Deleting the temporary .fndb files C:\Users\XXXX\AppData\Local\MiKTeX\2.9\miktex\data\le worked for me.
