Very funny installation! Is this a final version?
1) They changed the installation script. If the databases was not created, you should go and create it. If I remember starting with v4.2, if the database was not created, the script was able to create it for you. It is a shame we lost the ability to let the script to create the database for us.
2) Look in attachment how bad is looking the layout preview. This is the Frontend after installation is done. If you look into the source code from line 12 to 85 there is content missing. For sure we can scary the customers with such of layouts
It is hard to realize v4.4.1 installer was OK and this one is not. Why you are making changes in files which were OK? With an XC5 gone with the wind and XC4 too stressed, What shall we say? Nothing for the moment
QT please make the right changes to get a professional installation script!
