Windows Vista is supposed to be a fair bit more secure than past versions of Windows. Whether it is or not I’ll leave up to people that know more about OS security than I do. However, a number of WoW players are having trouble getting patch 2.3 to install on Windows Vista. The problem? Security!
Here’s the deal…The patch downloads correctly but when downloader completes and fires off the installer – the install fails. The problem – is one of permissions.
Most Vista installs are setup in such a way that the average user you are logged in as is not an administrator of the machine. If you’re not an administrator – you can’t install or patch software.
The solution is simple. Right click your World of Warcraft icon and select “Run as administrator”. This will start WoW running with administrator permissions instead of your local users permissions. The system will run through the patch process – but this time when the installer fires off, it’s running as an admin. The game should patch correctly and you’ll be pWning in no time!
