After installing ES4, when starting the configuration manager, I'm notified that some ear files are missing and I have the list of impacted modules. Later on when merging the ear files, I run into an error with code ALC-LCM-010-201 and therefore cannot finish the configuration.
I'm using Windows 7 Professionel 64 bits.
Note also that I'm not able to uninstall ES4. When clicking on the uninstall button nothing happens.
