I encountered the following while trying to process my PDF document from LaTeX, MiKTeX 2.9

Trying to make PK font mathkerncmssi8 at 600DPI...

Running miktex-makemf.exe... 

miktex-makemf: The mathkerncmssi source file could not be found. Running tt2pk.exe...

make-makepk: PK font mathkerncmssi8 could not be created.

Process exited with errors


This may be due to MiKTeX not having the map file activated.

Try adding the following to your document's preamble and see if it generates:


If it works, then you should update MiKTeX's font maps.


This worked for me when I had a similar error.

Simply navigate to your miktex bin directory and execute the commands below:

  • e.g. c:\Program Files\MiKTeX 2.9\miktex\bin\
  • initexmf --mkmaps
  • initexmf --update-fndb

as described in: https://www.dev-eth0.de/blog/2016/11/13/latex_miktex-makepk-pk-font-umvs-could-not-be-created.html

  • The second command is properly initexmf --update-fndb Other than that, this is a perfect answer to this problem. – SteelAngel Jan 23 '15 at 3:04
  • I required adding --admin to the commands, after initexmf – user5155835 Apr 7 '18 at 13:56
