The installation exe file doesn't work. I have check the installation with different kind of target for resources like Mysql, MariaDB and MariaDB embedded, and I get the same error. During the installation process folder Knowage with subfolders is created, and then database is created but empty since it can't load resources. I think the problem must be inside that installation exe file from Aprill 28th.
I have first issues of 8.1.RC from April 22nd and the installation works, but the application is not complete yet, application is missing some functionalities.
