Was Gloran component 0 installed? If not, then that should be the reason. Try to install Glorans component 0 manually and resume.
And make sure that the English translation is in the gloran\tra-folder. If it's not in there, use the English BiG World textpack and let it insert the language.
Edit: I'd say you need component 0 after looking at the debug-file. Just execute setup-gloran.exe in your
BG2-folder and let it install gloran but skip Gloran & Virtue. Then let the BWS try to resume / install the component.
