I have a problem. When I start pdfLatex using the package media9, there comes this error:

The required file tex\latex\l3experimental\l3str\l3regex.sty is missing.

So, I have downloaded the package l3experimental, but there is no path like this: l3experimental\l3str\l3regex.sty and l3regex.sty doesn't exist (only l3regex.dtx).

So, I have adjusted accordingly the path and renamed the file format into sty, but the error doesn't disappear.

Can You help me, please?

Welcome to TeX.SX! What operating system and TeX distribution are you using? –  egreg Jan 21 at 17:07
    
I use miktex on windows 7, 64 bit –  Jack Jan 21 at 17:14
    
@egreg: Backslashes in the given paths reveal Win as underlying OS. Maybe some outdated MiKTeX is running on it. –  AlexG Jan 21 at 17:15
    
@Jack Update to MiKTeX 2.9, if you haven't, and use its package manager for updating packages. Don't install them by hand. –  egreg Jan 21 at 17:19
    
Updating MiKTeX should also include an update (synchronize) of the package data base. See: tex.stackexchange.com/a/107528 –  AlexG Jan 21 at 17:24
