# Problems installing LaTeX packages

I'm running TeXnicCenter 1.0 and have just started in LaTeX. I have managed to get text in, get a lot of the formatting commands working and have rendered to pdf. It's awesome. My problem is packages, specifically `wasysym`. I have been googling and tried:

• placing `wasysym.sty` in `C:\Program Files (x86)\MiKTeX 2.8\tex\latex\wasysym`
• placing `wasysym.sty` in the folder containing the document file
• running Refresh FNDB from `mo.exe` - I get a permission denied error.

No matter what happens, whenever I try to render a file containing `\usepackage{wasysym}` it refuses to render. I don't know enough about the error messages to work out what's happening. Can someone please help?

PS I don't have trouble with standard/built-in packages like `parskip` etc. Just when I tried to install `wasysym` it threw a tantrum.

According to the MiKTeX list of packages wasysym comes with MiKTeX: miktex.org/packages/wasysym; did you try using the Package Manager to install the package automatically? – Gonzalo Medina Mar 27 '11 at 1:49
It wasn't working automatically, so, assuming it wasn't a standard package, I went to CTAN and downloaded it. After a bit of playing around with the ins file I got the .sty and placed it in the two places mentioned above. I get a fatal error every time I un-% the line calling the package. – JackSprat Mar 27 '11 at 1:56
One option would be to carefully remove the file(s) that you manually installed and then use the Package Manager from MiKTeX: here's the manual: docs.miktex.org/manual – Gonzalo Medina Mar 27 '11 at 2:08
Specifically, this could be useful: Working with the Package Manager: docs.miktex.org/manual/pkgmgt.html – Gonzalo Medina Mar 27 '11 at 2:15
Don't use texniccenter if you want to install missing packages on-the-fly. texniccenter blocks the installation. Use e.g. for one compilation texworks (which comes with miktex). You can also use the package manager to install packages. Beside this: for a manual installation it is not enough to install `wasysym.sty`, you need also the font (tfm, pfb-files) and you must activate the map-file. At last: if you get an error message you should copy it in your question. You may not know what it means - we do. – Ulrike Fischer Mar 27 '11 at 8:46

As @Gonzalo Medina has pointed out, `wasysym` is included im MiKTeX. Even if it wasn't, you should not manually place files in `C:\Program Files (x86)\MiKTeX 2.8` -- either use the package manager, or place all necessary files in your working folder (as a temporary solution) or a local TEXMF tree.
One possible reason for the "permission denied" error you mentioned is that your operating system is Windows 7 and you try to run the package manager and/or the `FNDB` refresh as normal user. Run it as administrator instead -- this option should be selectable under (Right-click) `Properties`/`Compatibility`. (Those may not be the exact labellings -- I'm using a German Win7.)
