It's a serious problem stop me using HB but I want to know how to fix it. When changing the EXE name I can run the 32 bit wow.exe, but with the file wow.exe you cannot run the 32 bit version but you can run the 64-bit version. Battle Client is not working either.
Why do you even change the .exe name? There is no need for that. You can rename or remove "Wow-64.exe" and then WoW always starts in 32 Bit Mode. You can also use our Launcher or set 32Bit in the WoW Launcher. Every way works.
