could not find qt platform windows

[peter99]

After the recent upgrade to world of warcraft, I can no longer start the game using launcher.exe. I can start the game using wow.exe, but I think that will only be temporary. I get the error message "could not find qt platform "windows" ".
Trying to start in a terminal, I get the following.

wine /media/peter/CAFC0C4FFC0C37E9/World\ of\ Warcraft/World\ of\ Warcraft\ Launcher.exe

Google shows that people are having the same problem, most cures involve changing wine config from win7 to winXP; this has not worked for me.
Any help would be appreciated
thanks

Do what it says; install winbind.
