如何运行 Springer 的 SVMult 类（显示错误）

Question

我正在使用 Winedt 编辑器。我正在尝试使用 Springer 的 SVMult 类创建文档。运行时，它显示未找到 SVMult.cls。我以前从未使用过此文档类，而且由于 .tex 文件太多，因此非常令人困惑。我附上了文件夹的屏幕截图编辑由 Springer 提供。

\documentclass[graybox, envcountchap]{svmult}

% 参考指南

\usepackage{mathptmx}        % selects Times Roman as basic font
\usepackage{helvet}          % selects Helvetica as sans-serif font
\usepackage{courier}         % selects Courier as typewriter font
%\usepackage{type1cm}        % activate if the above 3 fonts are
\usepackage{makeidx}         % allows index generation
\usepackage{graphicx}        % standard LaTeX graphics tool
                         % when including figure files
\usepackage{multicol}        % used for the two-column index
\usepackage[bottom]{footmisc}% places footnotes at page bottom
\makeindex

我尝试编辑名为“editor”的 .tex 文件并运行它。但它显示错误。请帮忙。非常感谢您的帮助。
