For me, im using Windows 10, and the there were 2 opcions to install the game, 1 was download Epilogue client and the the updater, or directly (the one i've choosen) was to download the launcher for full instalation... check it out again, delete everything, go to ur instalations game folder, and delete the posibly remaining elements, and use the launcher only, its about 22/23 GB of data, and its working fine for me since they improved the proxys...
