Delete this folder:
C:\Program Files\InstallShield Installation Information\{CFBCE791-2D53-4FCE-B3FB-D6E01F4112E8}

Then open regedit (Start > Run... > regedit) and delete these entries:
HKEY_LOCAL_MACHINE\SOFTWARE\Firaxis Games\Sid Meier's Civilization 4
Hey I'm having a similar problem with Civilization IV: Beyond the Sword. After entering:

C:\Program Files\InstallShield Installation Information\{CFBCE791-2D53-4FCE-B3FB-D6E01F4112E8}

into the search, I realised that it was specific to the original Civilization IV, as are the registry settings. Is there any chance that you could give me the corresponding directions for BtS? Thank you.
Never mind - I figured it out myself! Thanks GVBN though for a push in the right direction!
after raking my brains for 2 hours i finally saw this post. tysm, it finally got this mess going the right direction.
The GUIDs are

Civ4: {CFBCE791-2D53-4FCE-B3FB-D6E01F4112E8}
Warlords: {3E4B349F-10B5-4586-9D99-489A90A8B228}
Beyond the Sword: {32E4F0D2-C135-475E-A841-1D59A0D22989}
Will I be able to keep all my saved game files?
I did the same thing, I tried playing civilization 4 game of the year edition (which all it has is a bonus video) online and it updated to that 1.74 and now the game won't run and I want to keep all my saved game files?
I am using windows vista.
I posted that reply for anyone that reads this thread in 2011.
I know most people have the 5th Civilization, lol.
So, anyone out there reading this thread?
I think the install will leave your saves alone, but don't know for sure.

Make backup copy of them just to be sure, you can find them somewhere under the in the My Documents\My Games\[SMC4|BTS|Warlords] folders.
i suppose you have to use the instructions from post #2, but substitute the BTS GUID from post #7
