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.

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.

You should install mh from MiKTeX's package manager, you'll have no problem. Why do you want to install manually a package that's in the distribution? –  Bernard Jul 3 at 1:52
@Bernard let's say rookies shoot their foot :p –  athos Jul 3 at 1:58
Hi. I try to install the mathtools from mh bundles in the package manager, but it shows 'Error response from server: 404' . May I know how to solve this problem? –  Idonknow Aug 26 at 4:06
@idonknow my problem was that in my company there was a proxy, it works perfect for browsers but seems the TeX update does not recognize it. Not knowing how to config TeX proxy, I did the update at home , where my WiFi has no proxy –  athos Aug 26 at 13:56

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)

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).


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

Edit 2

Oct 1, 2014: could not find either mh bundle or mathtools package in the Package Manager (Admin)

It started to download and failed : "connect failed in tcp_connect()" -- I'm behind a firewall, may I check how to set the proxy? –  athos Jul 3 at 2:04
@athos Try again, and make sure you have a good internet connection or choose another download server (mirror). –  skpblack Jul 3 at 2:10
do you mean that i don't need to set up the proxy server ip etc? mmm, if so i guess the reason is the proxy prohibited some files (.exe or too big file), let me try it at home. –  athos Jul 3 at 2:23
@skplack thanks! it's working :) –  athos Jul 3 at 18:19
So... no longer possible to use mathtools at all? Your Oct 1, 2014 edit is not very clear to a tex noob. –  romkyns Oct 6 at 23:10
