Read through this thing but didnt find any similar issues that I am having.
Got Civ 4 + BTS ( real disks - also using Vista )
Installed the Civ IV, then tried to install BTS.
Got the message about missing patches. So I logged into the Civ IV game and check "latest update" and found I was missing 1.74. I DL 1.61 to obtain 1.74 patch from firaxis.com site.
I goto install BTS again and it goes to the same spot where I found out I was missing the Patches, but insted of error, the Game just dissapears.
I tried this again, but used the "Ctrl Alt Delete" to see what programs are running. Nothing was running intill i tried to install BTS, went to the same point then it disapeared again and lost it on my programs running Queque.
I think I saw a msg (came and went fast) that says something about checking DirectX, before I lost the Civ IV BTS download screen.
I have all windows updates possible from what I read to do before trying to Load Civ IV from disk.
Even though my Laptop has nothing running in its Queque, there was something that was still working. So I let the Laptop sit and hope that maybe it was thinking long and hard to pull up the next step. . . gave it 5min then looked in "my computer" for any hint of BTS, nothing. Went back to firaxis.com to update BTS patches 3.17, Cannot download until BTS has been installed. So that tells me it wasnt added.
I have 2 Disks for BTS and it has not asked ever for the 2nd disk.

--edit--
I did see someone mention something about Vinilla on this Topic, I do not know what that is, nor am I sure I have that. Is that required?
