Wow hangs on updating setup files
If on Vista you might want to do a Right Click- Run as administrator.
The version number down the bottom of the PTR login screen should read "Version 0.01 (8874)" 10) Login and it should download the downloader for Wo W-0.3.0.10522-en . If you've already downloaded it from a mirror or had it backed up from before just quit the downloader and copy that file into your "World of Warcraft Public Test" folder (replacing the one the downloader started to download).
For Mac OS X replace with 0) If you are reinstalling drag any files starting with "Wo W-0.3.0" in your "World of Warcraft Public Test" folder to a safe location EG the desktop. This step is to make sure your registry is all up to date 3) Run the downloader file (Wo W-220.127.116.1174-PTR-US-Installer-downloader.exe) .
1) Delete any and all "wowtest" and "World of Warcraft Public Test" folders you may have. It will ask you for a location for where to put the "18.104.22.16874 US PTR Installer" folder.
2) If on an OS that allows you to do so go to your Live Wow folder and right click the program there. Please remember where you put this folder for the next step.
9) Run the PTR from that folder by opening the Green Test icon.HOW TO INSTALL THE PTR IF YOU HAVE A PTR FOLDER FROM LAST TIME SCROLL DOWN IF INSTALLING FOR THE FIRST TIME: This is copy and pasted from last content patch we had. Please note I don't know what all the patch file names are as mirrors aren't up yet for me to check against.Also this guide assumes you want to reinstall the PTR hence step 1.This will allow do a integrity check on the file you downloaded.
11) If the Launcher from the "World of Warcraft Public Test" folder isn't running then open it.This should automatically open Wo W-0.3.0.10522-en program or the Background .
