[Tex/LaTex] the memory dump file could not be found

errorsmiktexwindows

I'm using MiKTex on Windows 8. Using the simplest tex file would bring about the error.

pdflatex.exe: the memory dump file could not be found.

\documentclass{article}
    \begin{document}
        Hello world.
    \end{document}

I've already tried suggestions in this forum as follows.

  • Start-> MikTeX 2.9 -> Maintenance -> Setting -> Open General tab -> maintenance -> update format -> I got a Permission denied in C:\Users\Kevin\AppData\Local\Temp .
  • Start-> MikTeX 2.9 -> Maintenance -> Package Manager -> Repository -> Synchronize -> I got a Permission denied in C:\CTEX\UserData\miktex\somewhere

Is is a permission problem in Windows 8?

Best Answer

Ok. I figured it out my self. It seems that permission is more strict in Windows 8. Or to say the default user is not the administrator.

I change the permission of user group in C:\Users\Kevin\AppData\Local\Temp and C:\CTEX\UserData\miktex\ to full control.

Every thing is sovled

If you want to solve it easily. You could run the text edit ide and MikTex as administrator or close your UAC once and for all.

Less secure is what it takes to get more convenience.
