Solution to the slow download of Battle.net
There are already two occasions in which I try to download the Battle.net application and the download is very slow, it stops and I have to retry again and again until I get to download the few megabytes it occupies.
To avoid this, I managed to get an official file, direct and less demanded, which downloads the same application but without downloading problems from the Blizzard distribution servers. The download url is the following: http://dist.blizzard.com/downloads/bna-installers/322d5bb9ae0318de3d4cde7641c96425/retail.1/Battle.net-Setup-esES.exe
I hope it helps you when you encounter the same problem when installing Battle.net
