Please help! They have updated my computer to Windows 7, and I have tried to reinstall MiKTeX2.9 and TeXnicCenter. When I run a LaTeX program, it tries to install 412 files from CTAN, and I get the error:

pdflatex.exe: A timeout was reached while receiving data from the server

And then I get a LaTeX error that pgfcore.sty was not found.

Is it some permissions problem with Windows 7? I have administrative privileges that I could use, but I don't seem to be prompted for my password...

This is driving me crazy! Any help is much appreciated.

Hi Fiona, welcome to TeX.sx! I removed the sign-off, as your user name and badge are automatically included anyway. – qubyte Feb 24 '12 at 17:33
Just as a single data point: The combination of Windows 7, MiKTeX 2.9 and TeXnicCenter (Alpha 4) is running nicely here. Try Ulrike's suggestions, if they are not enough I would completely remove MiKTeX and reinstall the full version. – Alexander Feb 24 '12 at 18:47

I doubt that it is due to permissions problems. The message says "timeout" and this indicates a connection problem. It could mean that the server/repository you are trying to use is simply down (that happens). But it also could be due to a proxy or a VPN-tunnel (I can't install packages on my work PC when I'm connected to our intranet).

Try to install the pgf-package directly with the package manager. Try different repositories (menu repository). If both doesn't work: Get from CTAN the files


and perhaps other package from systems/win32/miktex/tm/packages/. Put them all in an empty folder outside your miktex. Then use the package manager to install them by using the folder as "local repository".
