%PROGRAMDATA% — system‑wide app data
%LOCALAPPDATA% — local app cache
%APPDATA% — roaming preferences and settings
%TEMP% — installation temp files
C:\Program Files (x86)\Battle.net — leftover program files
Then restart your PC to clear anything held in memory.

Run the uninstaller as Administrator – Right-click the uninstall tool (or Windows Settings) and select “Run as administrator”.
Use IObit Uninstaller’s Force Uninstall – This bypasses the broken uninstaller and removes Battle.net even when it’s corrupted.
Boot into Safe Mode – Prevents third-party processes from interfering, then uninstall normally.
