+# TROUBLESHOOTING COMMON INSTALLATION ISSUES
+# =============================================================================
+
+# Issue: "Failed building wheel for PyQt5"
+# Solution: Install pre-compiled binaries
+# pip install --only-binary=all PyQt5 PyQtWebEngine
+
+# Issue: "Microsoft Visual C++ 14.0 is required" (Windows)
+# Solution: Install Microsoft C++ Build Tools
+# Download from: https://visualstudio.microsoft.com/visual-cpp-build-tools/
+
+# Issue: "vlc.dll not found" (Windows)
+# Solution: Install VLC media player system-wide
+# Download from: https://www.videolan.org/vlc/
+
+# Issue: "No module named '_ctypes'" (Linux)
+# Solution: Install libffi development package
+# sudo apt install libffi-dev
+
+# Issue: Segmentation fault on startup (Linux)
+# Solution: Install additional Qt libraries
+# sudo apt install python3-pyqt5.qtwebengine
+
