| Error 0x80070005 | Missing admin rights | Run as administrator |
| Installer runs but app still doesn’t work | App requires newer version | Download latest offline installer; WebView2 does not support downgrade without uninstall |
| Silent install hangs | Anti-virus or blocked exe | Run with /log to see stuck step |
| ARM64 installer on x64 PC | Wrong architecture | Use correct arch for target system |
