Hi,
I haven’t been able to install the batlle net app for windows for about a month now.
I have tried everything but the problem still persists.
Just for info, it all started with my Overwatch game update not starting (fetching encoding table) and one of the solutions was to reinstall the battle net app.
Thanks for any help! 
Hey there Cokognito,
Try the steps mentioned in here, as they might help.
Additionally this error seems to be caused by Razer software. If you have any Razer products it may be a good idea to make sure that the software that you use is updated.
Thank you very much, but unfortunately it didn’t help 
Hey Cokognito,
Sorry to hear that.
In that case it might be a good idea to reach out to our support, and provide to them some system files.
