  • Hey there METALACE!

    So there could be a couple of things going on here, from a security program to a network issue to an issue with the Battle.net Application itself. Let's start with the client and work from there:

    Perform Steps 1-5 of this article.

    Do not reinstall yet but follow these additional steps:

    1. Open file explorer/file manager
    2. Type the following into the address bar (not the search bar): %APPDATA%
    3. Delete the Bnet and blizzard folders inside the appdata folder if they exist.
    4. Repeat steps 2 and 3 with %LOCALAPPDATA% and %TEMP%
    5. Empty the recycle bin.

    Now reinstall the app to the C: Drive and have it relocate your games. This should get you around the issue at hand.
