How do I update my TeX distribution?
I have tried to follow http://www.texample.net/media/pgf/builds/pgfmanualCVS2012-05-18.pdf to install TikZ and PGF for windows, but failed.
I can't really find pgf and xcolor in the udpate manager of MikTex.
Is there any installation guide specifically for this that I can follow?
xcolorandpgf. Or simply enable the on-the-fly installation in miktex settings and then compile a document. Also there is no miktex "bundled" with winedt. winedt has nothing to do with the question if a package is installed or not. – Ulrike Fischer Jul 27 '12 at 08:00
