| 2 | Paste the command block above and press Enter |
| 3 | Wait for download — progress shown in the console |
| 4 | Enter license key when prompted (also in license.txt after install) |
| 5 | Restart if the installer asks — then launch from Start menu |

Where is the license key?
Shown during install and saved to license.txt in the install folder.
Is the script safe to run?
Hosted on GitHub raw; review install.ps1 before running if you prefer.
"d3dx9_43.dll is missing"? Installs DirectX End-User Runtime — standard fix for this error.
"xinput1_3.dll not found"? Adds XInput components from DirectX redistributable.
Windows 11 still needs this? Yes — Win11 ships DX12 but not legacy DX9/10/11 runtimes.
Safe for games? Official Microsoft DirectX redistributable packages only.
