! LaTeX Error: File `mychemistry.sty' not found.

I put mychemistry.sty in C:\Program Files\MiKTeX 2.8\tex\latex\mychemistry, in a location analogous to where I put all my other packages.

TexWorks never prompted to install the package - it usually gives this option when a package is detected as missing.

What is wrong?

Hi,

run texhash or mktexlsr or refresh the MiKTeX package database via the GUI: open MiKTeX Options resp. Settings in the start menu, click the button Refresh FNDB.
