Got to where it stopped and asked me to launch the game, make a character and a save. I did. But again the UI was messed up and I couldn't see the continue button. So restore from a backup of the directory and try once again. This time the continue button showed up, but the installer/script just closed down or crashed as soon as I hit continue. From the Weidu log, it certainly wasn't finished. I'm doing an install with about 70 mods (just about everything there is) and Weidu had only installed 27 before shutting down with no obvious error in the log.
Now I get to restore the backup of the directory and try once more.
Just to make sure, what you posted was the weidu.log from the EET part that is installed to BGEE prior to EET doing its job. That one looks fine and finished. What is in your BG2EE weidu.log?
