Recently I allowed Windows 10 to perform a major update. But now there seems to be a problem with the MiKTeX automatic package installer. E.g. I want to use package skak. So I include
pdflatex. Then that dramatic orange box:
Do you want to allow this app from an unknown publisher to make changes to your device? MiKTeX Package Manager.
So I click
YES. Then in the PDFLaTeX console:
! LaTeX Error: File `skak.sty' not found. Type X to quit or <RETURN> to proceed, or enter new name. (Default extension: sty)
All I can do now is hit RETURN. Compilation continues with the now expected undefined control sequences. After the last one the dreaded window pops up
pdflatex.exe has stopped working ...
