# ! ==> Fatal error occurred, no output PDF file produced!

I just updated my Windows 10 with a couple new security updates. However after rebooting the system none of my .tex will produce a PDF. I leave you the error message:

! I can't write on file letrasgoticas.pdf'.


Please type another file name for output ! Emergency stop. <to be read again> \endgroup \set@typeset@protect l.12 \end{document} *** (job aborted, file error in nonstop mode)`
