Installer uses resources with same name (differ only in case) -> doesn't work on Windows
Summary
The source code of the easy installer contains images like "Sad.png" and "sad.png" which on Windows systems are the same file (file names are case insensitive).
The problem
The source code cannot be fully cloned on windows systems (only one file "survives"). As a consequence, a Windows version of the installer would not be able to show all the intended resources.
Solutions
All files that exist with names that only differ in case need to be renamed before the code/installer works on Windows.
