 this is the line .. 
 <input type="button" class="button" name="btn_download" value="Download" onClick="if (!$('isys_form').down('[name="download"]').getValue().blank()) {$('isys_form').submit();}" />

 I had the same issue and decided to download the 1.12.3-update zip package manually. After extracting it in i-doit document root, the download button is not needed any more and you can go on installing it.

 Hi, 
 that hotfix doesn't work for me. After replacing the containing "2.tpl" the download button still does nothing...
