error while installing extension

there is a error called Error! Could not find a Joomla! XML setup file in the package.while installing the module in joomla1.5. there is the xml file but the version notified in the xml file is 1.6. Is it becoz of that.How can i solve the problem.the module that i downloaded is from http://extensions.joomla.org/extensions/structure-a-navigation/menu-systems/开发者_开发技巧select-box-menus

Since there is only one 1.6 native extension on that page I will assume you are installing Simple Select Box. There are versions depending on which version of Joomla you are using. The correct download for J!1.5 is here - http://joomlacode.org/gf/download/frsrelease/10339/40125/mod_SSB_1.5.4.zip
