Why uninstalling can fix DLL issues
- Version conflicts: bundled DLLs inside an app’s folder can override system versions and cause errors.
- Corrupted installs: broken updates leave invalid file paths or registry entries.
- Clean re-install: reinstalling refreshes dependencies and restores the right DLL versions.
Caution
Don’t remove shared runtime dependencies (e.g., Microsoft Visual C++ Redistributables) unless you’re certain they aren’t needed. See Official Redistributables.
