nvidia 8600M graphic card, using nvidia binary 190.42 drivers.
wine version 1.1.33.
World of warcraft installer v1.4.0.250.

I have a fully working wow installation, but when trying to use 'installwow.exe' from wow webpage to download/install wow burning crusade expansion, dialog appears trying to download but after about 10-15 sec, get error message "Failed to download world of warcraft installer. Please close all applications and try again". 

Here is the console output!

Have also tried use 'env WINEPREFIX="/home/username/.wine" wine installwow.exe'.
