If i run the installer with "wine EAappInstaller.exe", it crashes like i explained before.
Now if i use this command : "LC_ALL=en_US.utf8 wine EAappInstaller.exe", the installation works.
Maybe you could change the title of bugreport to reflect the problem. FWIW: I tried run with LC_ALL=fr_FR and the installer still succeeds (used staging 6-20) I guess there`s some kind of vague issue on your side?
