When a developer compiles an application that to this function, the compiler generates an import entry in the executable's PE (Portable Executable) header. When that executable runs on Windows 7, the operating system's loader attempts to resolve the import address—and fails. The result is the familiar error dialog:
This left developers with an ugly choice on Windows 7:
if (pGetSystemTimePreciseAsFileTime) pGetSystemTimePreciseAsFileTime(ft); else // Fallback logic for Windows 7// Combine GetSystemTimeAsFileTime with QPC Performance and Pitfalls getsystemtimepreciseasfiletime windows 7 patched
) require this function, Windows 7 users often encounter "Procedure Entry Point Not Found" errors. VxKex (Kernel Extensions for Win7) : An open-source project (found on
The most promising avenue is that the two functions have identical signatures. This means a patcher can potentially modify the executable's Import Address Table (IAT)—the list of functions the program requests from DLLs—to substitute the missing function with the universally available GetSystemTimeAsFileTime . Several tools can accomplish this: When a developer compiles an application that to
High-Precision Timestamping on Windows 7
If your software does not require the precision of the new API and can build with an older standard, you can fix the issue at the compilation stage: VxKex (Kernel Extensions for Win7) : An open-source
Simulating high precision on Windows 7 via QueryPerformanceCounter is computationally more "expensive" than the native Win8+ function.
void InitHighPrecisionClock(HighPrecisionClock* clock) clock->has_qpc = QueryPerformanceFrequency(&clock->qpc_frequency);
The infamous error is one of the most common blockers for running modern software on Windows 7.
