title: What is the order of load AutoCAD plugins?
body: <p>There are few ways of automatic load applications - plugins when AutoCAD starts. I know those:</p>
  
  <ul>
  <li>startup suite - attached by GUI</li>
  <li>List item <code>%appdata%....\support\zwcad2018.lsp</code> ( I use ZWCAD, maybe in Acad, there is another path. The long time ago when I worked on Acad it was acad.lsp, but that was times before Windows UAC feature).</li>
  <li><code>*.mnl</code> loaded while corresponding *.mnu is loaded ( old fashion way, but is ZWCAD possible) what about Acad?</li>
  <li>On-demand loading: <code>HKEY_CURRENT_USER\Software\ZWSOFT\ZWCAD\2018\en-US\Applications\MyApplicationName</code> </li>
  <li><code>zwcaddoc.lsp</code> if the path to my application is in Options/File/Support File Search Path </li>
  <li>application shortcut using <code>/ld</code> switch</li>
  <li><code>acad.rx</code> </li>
  </ul>
  
  <p>What is the order of ways to load applications?
  And if there are other ways not listed here please let me know.
  Probably ARX or .Net applications may be loaded also in another way. </p>
