: You can cross-compile for older targets using custom build scripts or leveraging an older compiler release channel (such as Rust 1.77 or below) that retains the GetSystemTimeAsFileTime fallback mechanism.
This missing function is currently the primary reason many modern apps no longer run on Windows 7, including: GetSystemTimePreciseAsFileTime error on Windows 7 #101 getsystemtimepreciseasfiletime windows 7 patched
Fall back to the standard GetSystemTimeAsFileTime . The Bottom Line : You can cross-compile for older targets using
Native Windows 7, however, lacks this function. Its closest alternatives— GetSystemTimeAsFileTime (millisecond precision, affected by time adjustments) and QueryPerformanceCounter (high resolution but not a true system time)—leave a gap for applications requiring both high resolution and a true UTC-based file-time format. Why the Error Occurs on Windows 7 Several
Introduced by Microsoft starting with Windows 8, GetSystemTimePreciseAsFileTime cannot be natively patched into Windows 7 through standard Microsoft Updates. Because modern toolchains like MSVC v145 , Rust 1.78+ , and Qt automatically bake this function call into compiled binaries, users attempting to run newer software on Windows 7 will inevitably encounter a load-time crash stating that the procedure entry point could not be located in KERNEL32.dll . Why the Error Occurs on Windows 7
Several converging trends have made this error increasingly common:
