MiKTeX and proTeXt ⇒ amsmath | Package Installation

[Rustam]

Good time of the day!

I updated MikTeX to latest version and I found that package amsmath is missing.

I tried to compile file with following beginning
and I have an error.

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

Code: Select all

\documentclass[12pt,titlepage]{report}
%\documentclass[12pt,titlepage,draft]{report}
\parindent=0cm
\usepackage[mathscr]{euscript}
\usepackage{mathrsfs}
\usepackage{amsmath,amsthm,amssymb,latexsym,amsfonts}
\usepackage{showkeys}

How I can fix this problem?

Start the MiKTeX Package Manager (MPM) and install the package subsequently.

I already tried this, but the problem is that amsmath is not in the list in Package Manager.
I have amslatex and immediately after this amsref.

It will probably be the same with the amsthm package. It's caused by a reorganization of the AMS files in MiKTeX. Have a look here:

• A MikTeX update may remove amslatex / amsmath as obsolete - how to fix it

You need to synchronize the local repository database, in the package manager, done via the menu: Repository→Synchronize.
