If you have your original SimCity 3000 CD in a box somewhere, you are legally entitled to a digital backup. You can use free software like PowerISO or WinCDEmu to create an ISO image of your disc. You then mount that ISO and install the game. However, you will still need fan-made patches (like the SC3UKernel Patch ) to get it working on Windows 11.
