Almost everything, see comments on what doesn't work. You will need mfc40.dll and mfc42.dll installed to the windows/system32 folder. Change font in metaeditor program settings if can't read font. Simley face for EA requires wingding font.
What does not
Changing EA settings can't be done through dialog box. Workaround is to edit preset file and load file. .set files edit fine with your favorite text editor.
History data doesn't download to systm correctly. Workaround is to import 1 min history from Alpari or similar and build other timeframes from 1 min data. Google it and you will several howtos on this subject.
