I'm a big fan of this community, since I always find an answer to my problems. Just not this time. I have a new computer (from my company) and I installed MiKTeX with the option of installing packages on the fly. I'm also using a Proxy Server to download the packages and I use TeXStudio. So far so good. It works for pretty much all the packages, but I get an error when I try to use the pgf package for tikz:
File 'tikz.sty' not found
The logfile gives the following error
I also downloaded the package myself, unpacked it, and added the root directory in the MiKTeX options... still doesn't work. I asked a colleague to try to install the package herself, and she got the same error.
Any Ideas how to fix this? Thanks in advance
