How to run 32bit WoW client

First of all use your brain. You can do it by yourself if you use it

Rename wow64.exe to something else wow32.exe for example

Rename Wow.exe to Wow64.exe

But this doesnt mean HB is going to work. What I understand is HB is looking for wow.exe process as it can't find wow.exe HB can no attach. At least 32 bit works. Don't fill forums with useless threads.

 

The problem is, that that method will be broken next time Blizzard Ninja-patches, releasethe data for an upcoming patch or something causing it to start downloading data.

The best way to do it it this:

Open your wow installation directory.
Create a shotcut on your desktop of the wow.exe (NOT the wow-64.exe icon)
Right-click the icon, and select Properties...
In the Target: text-box, after the complete path to your wow.exe (for instance: "C:\Users\Public\Games\World of Warcraft\Wow.exe")
Add -noautolaunch64bit after the last " ("C:\Users\Public\Games\World of Warcraft\Wow.exe" -noautolaunch64bit)

That way you will ALWAYS launch a 32 bit version of WoW when you click on your shortcut, and you don't have to delete or rename anything, and the link will alaways launch the correct version even if your install directory gets updated.

 

seems like they fixed "run in 32-bit" option in launcher again btw!
