I had an issue with installing the "WoW-3.3.0.10958-4.0.0.12911-NA-FULL" it kept saying
World of Warcraft could not be found. Please make sure the game is properly installed.
after some digging ( I already applied the tips you suggested)
Copy "base-Win" to the "Data" folder
Edit realmlist.wtf
Edit or create launcher.wtf in the "WTF" folder
SET downloaderTags "EXP3,EXP2,EXP1,Win,enUS"
SET expansionLevel "3"
SET locale "enUS"
SET downloadCompleted "0"
SET patchApplicationCompleted "1"
SET requiredCompleted "0"
SET userspeed "1268770"
SET accountType "CT"
and it turns out that in order for the "WoW-3.3.0.10958-4.0.0.12911-NA-FULL" patch to recongnize the wow install you MUST run the launcher.exe as admin so to take percauction I unplugged my internet from my pc... but turns out your launcher.wtf took precedence and a lilttle WotLK logo appeared and went right in to wow.exe.. I thus closed the game client and ran again "WoW-3.3.0.10958-4.0.0.12911-NA-FULL" WoW-x.x.x.x-4.0.0.12911-Updater.exe and it detected and is now patching.
I just thought I'd mention this in hinde site becuase
See the issue is my wow install is from Vanilla (patched to 3.3.5 over time) and from XP... and i'm on a completely different system, than I was back on my AthlonXP.... and Windows 8 and i've brought that install with me everywhere... multiple backups, cpu's video cards types of RAM... and ever OS under the sun (windows based from XP including server OS's ) sadly i never backed up Vanilla or BC cleans.. to much regret...
