Help with manual install

[a3des]

I get some error durin install in Themes/default/index.template.php
I had a close look on the file, prepaired myself to manual install and I got stuck like the package installer when I reach to following modification:
Find: [Select]
                     </td>
Add After: [Select]

                     //Welcome Ads
                     if (function_exists("show_welcomeAds"))
                     {
                        $ads = show_welcomeAds();
                        if(!empty($ads))
                        {
                           echo '<td class="windowbg2">';
                           if($ads['type']==0)
                              echo $ads['content'];
                           else
                              eval($ads['content']);
                           echo '</td>';
                        }
                        unset($ads);
                     }
                  echo '

Well the problem is I cand find "                     </td>" to execute the modification. I have many </td> but none as requested so can someone be more specific, about wich </td> is this about.

Thank you very much in advance.
