I understand you're looking for Keil uVision 3 for Windows 10. However, I need to give you some important context before providing a direct download.
Post-Installation Stability Getting the software installed does not guarantee a smooth workflow. uVision 3 lacks the High-DPI awareness of modern applications, often resulting in a blurry, stretched interface on modern 1080p or 4K monitors. More critically, driver issues plague the debugging process. While the IDE itself might run, communicating with legacy debugging hardware (like older ULINK probes) via USB on Windows 10 can be problematic due to modern driver enforcement policies. Users may need to disable Windows Driver Signature Enforcement to interface with older hardware development boards—a security compromise that is not ideal but necessary for legacy development.
Known issues and limitations
Keil uVision 3 is a legacy Integrated Development Environment (IDE) widely used for programming 8051 microcontrollers and ARM legacy devices. While it has been succeeded by uVision 4 and uVision 5, many developers and students still seek version 3 for compatibility with older codebases, specific hardware debuggers, or academic tutorials.
