I use Texstudio and Miktex on Win 7 as a portable version.
Today i updated my miktex-packages and everything worked fine except the "\usepackage{tikz}" command.
I made a fresh reinstall with the newest versions of miktex and texstudio, opened my latex-document and compiled it. Miktex installed all missing packages on-the-fly except pgf/tikz, wich gave an error instead. I installed it manually in the package manager but texstudio still says "File "tikz.sty" not found".
Unfortunately I have to use the portable version, because I don't have any admin rights. The last time I worked on that document, everything worked fine.
Any ideas?

The MikTeX package
pgfis broken, it doesn't contain any files.In such cases the right thing to do is to check the issues at https://github.com/MiKTeX/miktex-packaging/issues and to add one if needed.
