Install problems on my Joomla version

I am trying to install the free version.
I keep getting install errors (can't find the XML) when I try to install your plugin.

My Joomla version is 1.5.15. Do you have a Mobile Jooma! extension version that works on my Joomla version?

MobileJoomla requires Joomla 1.5.26 or higher (actually ~1.5.20 is sufficient, but we test it in 1.5.26 only).

just unzip the file before install its joomla folder not find xml file if u have unzip the extension its easy to install
