# the memory dump file could not be found

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?

Restart your computer and try again. I know it may sound like a non-solution, but have you tried it? Give some feedback as to whether that resolved the problem or not. –  Werner Nov 7 '12 at 3:40
Also Windows 8 is very new. Don’t forget, that many people still running Windows XP, but the most Win users have Windows 7, I guess. In short: If it is specific for Windows 8, all these cannot give help. –  Speravir Nov 7 '12 at 3:47
Christian Schenk, the MiKTeX developer, tested about one year ago the preview of Windows 8 and seemed not to have encountered any problems: MiKTeX on Windows 8. So abit more information by you is necessary: Where did you install? Take a look on user permissions because: For me the answer to your question in the moment is “Yes”. –  Speravir Nov 7 '12 at 16:22
I tried restart computer as well as reinstalling MiKTeX. It seems the permission issue indeed. I figure it out myself. Hope to help anyone else. –  Kevin Tong Nov 8 '12 at 6:58
Same problem occurred to me in windows 7. I actually installed TexStudio and Miktex in F drive. After loading a new windows 7 OS in c drive, I change the path environmental variable and it worked fine. But now showing 'the memory dump file could not be found' error. I tried it in administrator mode, but the same problem is there too. –  user35822 Aug 28 '13 at 3:06

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