Fixing Cannot Stream required archive Data / WoW Error 134, on Cataclysm 4.3.4
Today's Cataclysm tutorial explains how to get rid of the frustrating Cannot stream required archive data, and in other cases, you might experience WoW Error 134, for Cataclysm 4.3.4
Why does the Cannot stream required archive data / WoW Error 134 Error even happen?
The reason is that the Cataclysm mini-client (fast client) depend on Blizzard's servers. This means that the client downloads from Blizzard's CDN Servers (Streaming Servers).
Until recently, they were public for everyone to download, but recently Blizzard has closed the access to it.
This means that your WoW Cataclysm Client is unable to download the necessary files, which results in the: "Cannot stream required archive data" error, and the WoW Error 134 on your Cataclysm 4.3.4 client, and in some rare occasions: the WoW Error 132.
Here's the solution to: Cannot stream required archive data / WoW Error 134
We need to replace the download location in your client, so your WoW 4.3.4 Cataclysm Client downloads it from a location that is accessible.
In order to solve the Cannot Stream required archive data, or WoW Error 134, you need to open your Cataclysm client and find the file called WoW.mfil.
After opening the WoW.mfil file on your Cataclysm client, delete everything in it. After doing so, insert this instead: [Hidden content]
Now you're almost done solving the frustrating Cata 134, Cannot Stream required archive data error.
The final step is that you should save the document, and launch your Cataclysm client.
After doing so, you will experience that your Cataclysm client is now launching correctly, without the error that you previously experienced.
