I've have none of the apps which may cause download problems downloaded. For example, ByteFence. 
The apps which may cause download problems i mentioned are in this website: https://minecraftirc.net/support-articles/known-incompatible-software/

Anyone know how to fix this 😞
I can't download any new version that i haven't downloaded.
