Installation of easyblog 5.0.30 fails - missing xml file

Hi,

I just downloaded the easyblog 5.0.30 and tried to install. Unfortunately all packages fail using the description on http://stackideas.com/docs/easyblog/administrators/setup/installation-on-joomla-3-x

Launcher package: (installed via Joomla Extension Mgr Upload package file, joomla version 3.4.5 )

Warning: JInstaller: :Install: Can't find XML setup file.
Error: Unable to find install package
Inspecting the com_easyblog_launcher_pro_5.0.30_joomla3.0.zip file it shows that it contains no xlm file (see screenshot)

Component package \com_easyblog_component_pro_5.0.30_joomla3.0.zip
transferred to server using filezilla to folder /components/com_easyblog/setup/packages

Warning: JInstaller: :Install: Can't find XML setup file.
Error: Path does not have a valid package.
Unable to find install package

same error when file is put in folder /tmp/easyblog

inspection of zip file: root does not contain xml file (see screenshot)

Full package com_easyblog_full_pro_5.0.30_joomla3.0.zip

same error , although file contains config.xml file (see screenshot)

can you please inform me what I am doing wrong ?
