For 100% reliable uVision 3 experience on Windows 10:
While Keil uVision 3 is not natively compatible with Windows 10, it can function correctly with Compatibility Mode and Administrator privileges. It remains a functional tool for maintaining legacy 8051 projects, though migration to uVision 5 is advised for modern development.
If you are not explicitly forced to use version 3 by an employer or instructor, upgrading to the latest version of Keil is highly recommended.
The most reliable method to run uVision 3 on Windows 10 is a using:
Using outdated development tools poses significant operational challenges.

The Complete Guide to Keil uVision 3 for Windows 10 Keil uVision 3 is a legacy integrated development environment (IDE) developed by Arm. It is designed for writing, compiling, and debugging code for older microcontroller architectures. Developers primarily use it to program classic 8051 variants, legacy ARM7, and ARM9 processors.
During installation, the setup might ask to install older USB drivers (like for the original ULINK). It is often better to this, as they will not work on Windows 10 and may cause system instability.
