I just installed Miktex (2.9, 64-bit, the default download) on this machine and tried using it with Texmaker but the compilation seems to crash. I tried running pdflatex from a terminal and got the following:

ERROR: Windows API error 87: The parameter is incorrect.

ERROR: Info:
ERROR: Source: Libraries\MiKTeX\Core\MemoryMappedFile\win\winMemoryMappedFile.cpp
ERROR: Line: 83

Does anybody know how to fix this? I tried reinstalling but it didn't help.

  • Normally this means that something is open, e.g. the console, and blocks the fndb. – Ulrike Fischer Jul 26 '18 at 12:59
  • @UlrikeFischer Oh, so I cannot use pdflatex while the console is open? Let me try.... – Anonymous20DB28 Jul 26 '18 at 13:03
  • @UlrikeFischer You were right! Would you mind adding this as an answer so I can accept it? – Anonymous20DB28 Jul 26 '18 at 13:06

Normally this error means that some miktex tool is open (today mostly the console) and blocks the fndb.
