I'm struggling to install the cancel package in TeXnicCenter . No success at all...
The cancel package belongs to C:\Program Files\MiKTeX 2.7\tex\latex\ltxmisc
I certainly see ltxmisc as "installed" in the MikTex package manager.
I also run the TeXnicCenter "Tools" => "Import Tex Commands" and imported such ltxmisc.
This action created an ltxmisc.xml file under C:\Program Files\TeXnicCenter\packages
Still, the TexnicCenter does not recognize at all the command \cancelto
Thanks a bunch!
