Beamer on MikTeX

Need xcolor and pgf for the new beamer to run. MikTeX kept failing on pgf install. Led to discovery of problem with MikTeX 2.6 and LZMA compressed package archive files. Had to update just the miktex-bin, then update the rest to get the latest package manager. Remember, don't have package manager and updater running at the same time - they access some same files and can lock each other out on windows.
