[Tex/LaTex] How to install mathtools package

installingmiktex

I'm new to Latex so forgive me if the questions are dumb…

I was trying to right left-top corner superscript, someone recommended mathtools package on this forum: Left and right subscript / superscript.

So I downloaded mathtools.zip from CTAN, unzip it, there's an "mathtools.dtx".
In the package there are documents but none talked about how to install, I fancy the installation is just too primary to real Latex users.

OK, then, there's still another thread here explained the steps: How can I manually install a package on MiKTeX (Windows) . So here I follow

  1. I ran "tex XXX.dtx" (there's no *.ins files) on all the .dtx files under the extracted folder, that includes: breqn.dtx, flexisym.dtx, mathstyle.dtx, empheq.dtx, mathtools.

  2. Then I created a folder "C:\athos\localtexmf\mathtools" and put all the new files in.

  3. Then I go to "Windows -> Start -> Programs -> MikTex 2.9 -> Maintenance (Admin) -> Settings (Admin) "; in "Roots" tab I added path "C:\athos\localtexmf"; in "General" tab I clicked "Refresh FNDB" and then clicked "OK" to close it.

  4. I restarted my WinEdt, added
    "\usepackage{mathtools}" under "\documentclass…"; and added "test $\prescript{14}{2}{\mathbf{C}}$
    " in the main body.

After that when I try to "MikTex", the error still comes up:
"The required file tex\latex\mh\mathtools\sty is missing. It is a part of the following pakage: mh . The package will be installed from …"

Seems the folder "C:\athos\localtexmf\mathtools" is not captured by MikTex?

Then in the error message dialog, I choose "Change", choose "Package shall be installed from a directory", click "Next", choose ""C:\athos\localtexmf\" or "C:\athos\localtexmf\mathtools", in either try it says "Not a local package repository".

What shall I do?

I'm on Microsoft Windows XP Prefessional SP3, WinEdt 8 (Build: 20140613 (v. 8.2) – 32-bit), and MikTex 2.9.

Best Answer

If you have installed MikTeX 2.9 (on Windows) is very easy. You can go to

Home->Programs->MiKTeX 2.9->Maintenance (Admin)->Package Manager (Admin)

Alternative path to admin exe file C:\Program Files (x86)\MiKTeX 2.9\miktex\bin

or without (Admin) if you want to install the new packages in a local directory. There you can choose any package and to install it by clicking in + button. In case of the mathtools package you can find it in the mh bundle (it appears in the list of installable packages) and provides a se­ries of pack­ages de­signed to en­hance the ap­pear­ance of doc­u­ments con­tain­ing a lot of math­e­mat­ics (mathtools included).

Edit

From August 19'th 2014 the mh bundle has disappeared in MiKTeX, now it's possible to find the mathtools package separately.
