Wont let me install (says communicationError)

Technical Support
Downloaded the install file to install wow on my desktop, and it fails to install because of "communication error"

I have restarted my pc, and removed the computer off the router so it is directly into the modem and still no go. Is there an issue with the blizzard patching server?


I have also re downloaded the file a few times incase it is corrupted but that did not work either.
Nvm, fixed it by deleting the old battle.net files on my computer.
