* If you were to install from scratch you would be installing : WoW 1.x.x -> The Burning Crusade 2.0.1 -> 2.4.0 -> 2.4.1
* If you install 2.0.0 Non-TBC and patch it to 2.4.1 before installing TBC, you will have to reinstall all the patches again. Luckily, you won't have to download them again, so the fastest path to take would be, WoW 2.0.0 -> 2.0.0 to TBC expansion -> 2.4.0 -> 2.4.1
* If you have multiple locales installed (for addon development or otherwise), you have to move or remove the extra locale folders from Data or the updater will die with a message that looks similar to this:
Cannot find data for {locale} locale.
WoW 2.0.0 is from none -> 2.0.0 installer. It's Non-TBC.
You DO need the 2.0.0 to TBC expansion (the contents of which are included in your retail TBC CD/DVD). If you update your client to 2.4.0 without the 2.0.0 -> TBC expansion, you'll lack expansion data.
Manual/Split Patches
* Manual patches: Unzip contents to your WoW directory and double click the file Blizzard Updater.exe or BNUpdate.exe to start patching. Blizzard Updater.exe and BNUpdate.exe check for ".Data{locale}" (the current directory), "..Data{locale}" (the parent directory), "....Data{locale}" (the parent of the parent directory), until it hits the root of the directory structure (where it informs you that WoW must be installed before it can be patched), for Game data (not tested on any paths deeper than "C

rogram FilesWorld of WarcraftPatches{patch folder}{patch data}"); therefore, you must put the patch files directly in the WoW installation folder or in a subdirectory of said folder. For example, the following all work for "WoW-2.2.3-to-2.3.0-enUS-patch.zip":
1. unzip the files to "C

rogram FilesWorld of WarcraftWoW-2.2.3-to-2.3.0-enUS-patch" and double-click "C

rogram FilesWorld of WarcraftWoW-2.2.3-to-2.3.0-enUS-patchBNUpdate.exe"
2. unzip the files to "C

rogram FilesWorld of WarcraftPatches" and double-click "C

rogram FilesWorld of WarcraftPatchesBNUpdate.exe"
3. unzip the files to "C

rogram FilesWorld of Warcraft" and double-click "C
