Even with a pristine ISO, errors occur. Here is the 2025.u1 specific troubleshooting guide:
| Error Code | Message | Solution |

| PASE 4096 | "Licensing module mismatch" | Your ISO is version 2025.u1, but an old Adobe PCD (Product Common Desktop) remains. Uninstall all Adobe apps, reboot, retry. |
