How to install a package on texlive? [windows 7]

Please start the TeXLive manager and you should get:

• In the Status-block you could select only installed packages. (marked as 1)
• In the column "Local Rev" (marked as 2) you can see the actual version.
• The column remote rev will contain the actual version of the remote repository (you must first load it). If there is a higher number, then there was an update.
• In the Block Repository you can load from a remote repository. This may take some time. The status block on the bottom will show you some details. (marked as 3).
  • If there is a problem, you may try to use a different repository. Select one from the menu under tlmgr
• With Update all installed you can refresh your installation.
• With Update you can update the selected entries. (You could select the status updates and select them).
• In the block Match you can set a filter.

As you do it the first time, you must first update the manager. Instead Update all installed there should be another command (sorry, I can`t provide a screenshot yet). Just follow the instructions. After the update of the TeXLive manager you have to restart it and then you can update your packages.

If you have problems, can you please post a screenshot, so we can see what your problem is.
