| Issue | Solution | |-------|----------| | “Missing MSVCRT.dll” or “VCRUNTIME140.dll” | Install Microsoft Visual C++ Redistributable . | | App crashes on scan | Run as Administrator (right‑click czkawka_gui.exe → Run as administrator). | | No results on large disk | Give it more time – hashing 500,000+ files can take minutes. | | Similar images finds too many false positives | Lower similarity threshold (e.g., 75%) or increase min width/height. | | Cannot preview videos | Install K‑Lite Codec Pack or VLC (Czkawka uses system codecs). | | GUI looks tiny on 4K monitor | Right‑click czkawka_gui.exe → Properties → Compatibility → Change high DPI settings → Override high DPI scaling (Application). | windows-czkawka-gui.zip
