Did it say:

tashia.mp3 - mpg123/w32 0.59s-mh2

??
PS: [Setup-A6CharmPatch.ese]?? Did you type that entire thing??

Yes and yes.

What do you mean replace the setup-x.exe with weidu.exe, how do I do that?

Yes, it had been stuck for hours, also the header or whatever didn't say c:\Windows\System32\cmd.exe any longer, but something with tashia.mp3 and something about KHz or bps, it all looked very odd and I concluded that it had stopped working.

I wiped everything from my HD earlier today, reinstalled both games, and I'm running it again now. This time I manually selected mods, so I have substantially less, hopefully reducing risk of failure.
The DOS window has been running for around 2 hours, however it does seem like it has stopped working, the last lines are:

WeiDU files in version order:
[Long list of mods]
Copying [setup-wheels.exe] -> [Setup-Assassinations.exe]: false
Auto-Updating on behalf of Setup-Assassinations.exe]:
[Setup-Assassinations.exe] WeiDU version 21100
{Setup-A6CharmPatch.ese} Queried <pid = 364>[WeiDU-Backup] WeiDU version 21300
[./CHITIN.KEY] 306 BIFFs, 61584 resources
[./dialog.tlk] 149939 string entries
[WeiDU-Backup] Using scripting style "BG2"

And like this it has stood for 30m+, has it stopped again or?

Question: How is the "Big World Install.bat" supposed to finish? Because mine stood for hours, and when I checked in on it it was no longer working and said something about tashia.mp3 in the header, it just seemed like it hadn't finished properly, the game isn't working either, it crashes immediately:

I have tried running it again, but the error repeats itself.
