The error "The procedure entry point GetSystemTimePreciseAsFileTime could not be located in the dynamic link library KERNEL32.dll" occurs because your software is trying to use a high-resolution time function that only exists in Windows 8 and newer.
Windows 7 does not natively support this specific API, and there is no official "patch" from Microsoft to add it. Common Causes for Users
Newer App Versions: Developers often update their tools (like Visual Studio) to use modern APIs, which can accidentally break compatibility with Windows 7.
Third-Party Libraries: Many modern applications use libraries like libuv or SDL that recently added calls to this function, causing crashes on older systems.
Qt6/Qt5 Toolchains: Programs built with Qt6 are particularly prone to this issue on Windows 7. How to Resolve the Issue 1. Use "VxKex" (Recommended for Power Users)
VxKex is a popular third-party tool designed to extend the Windows 7 kernel. It acts as a wrapper that "fakes" the presence of newer APIs like GetSystemTimePreciseAsFileTime, allowing modern programs to run without modification.
How to use: Install VxKex, right-click the application's executable, and enable "VxKex" in the compatibility settings. 2. Downgrade the Application 14.6 doesn't support Win 7? - FreeFileSync Forum getsystemtimepreciseasfiletime windows 7 upd
The direct answer is that the GetSystemTimePreciseAsFileTime error occurs because this API was introduced in Windows 8 and does not exist in the Windows 7 version of KERNEL32.dll. When modern software or runtime toolchains (such as the latest MSVC Platform Toolsets, Rust, or newer Qt frameworks) are updated, they drop Windows 7 compatibility and invoke this function, causing applications to crash instantly with an "entry point not found" error.
🛠️ Why the "GetSystemTimePreciseAsFileTime" Error Occurs
The core of the issue is an operating system version mismatch:
High-Precision Time API: The GetSystemTimePreciseAsFileTime function provides highest-possible precision (less than 1 microsecond) for system time. Microsoft introduced it in Windows 8 and Windows Server 2012.
No Native Windows 7 Export: On Windows 7, the core system library KERNEL32.dll only contains the older GetSystemTimeAsFileTime function. It completely lacks the higher-precision variant.
Modern Toolchain Updates: If you install an update for an application or a game, and the developer has compiled that update using a newer compiler (like MSVC v145 or Rust 1.78+), the binary will automatically link to the newer API. This makes the software unusable on Windows 7. ⚙️ Best Workarounds and Fixes for Windows 7 Users Load the function pointer safely and fallback if
Since Microsoft has officially ended support for Windows 7, there is no official OS update that will add GetSystemTimePreciseAsFileTime to the legacy KERNEL32.dll. However, there are several reliable workarounds available: 1. Downgrade to an Older Software Version
The most reliable way to run the software without modifying your system files is to install the previous release that still maintains Windows 7 compatibility.
Identify the Breaking Update: Check the software's release notes or GitHub repository.
Download the Legacy Version: Download a version compiled prior to the toolchain update (for instance, older versions of tools built using Qt 5 or older MSVC toolsets). 2. Use VxKex (Extended Kernel for Windows 7)
For advanced users who absolutely need to run modern applications on Windows 7, a third-party compatibility layer is an effective solution. GetSystemTimePreciseAsFileTime error on Windows 7 #101
There is no official Windows update to add GetSystemTimePreciseAsFileTime to Windows 7. This function was first introduced in Windows 8 and is not present in the kernel32.dll of older operating systems. #include <windows
If you are seeing an error like "The procedure entry point GetSystemTimePreciseAsFileTime could not be located," it usually means a modern application or toolchain (such as MSVC v145) is trying to run on an unsupported system. Potential Solutions and Workarounds
#include <windows.h>
typedef VOID (WINAPI *GetSystemTimePreciseAsFileTime_t)(LPFILETIME);
void GetPreciseOrFallbackFileTime(FILETIME* ft)
HMODULE hKernel = GetModuleHandleA("kernel32.dll");
if (hKernel)
GetSystemTimePreciseAsFileTime_t pGetPrecise =
(GetSystemTimePreciseAsFileTime_t)GetProcAddress(hKernel, "GetSystemTimePreciseAsFileTime");
if (pGetPrecise)
pGetPrecise(ft);
return;
GetSystemTimeAsFileTime(ft); // fallback for Windows 7 / older
Notes:
Yes, you can use GetSystemTimePreciseAsFileTime on Windows 7 – provided you have installed a specific servicing stack update.
Released in February 2013, this update was primarily aimed at improving DirectX 11.1 support, but it also brought several system API enhancements, including:
GetSystemTimePreciseAsFileTime back-ported to Windows 7.Ensure that your system time is synchronized with a reliable NTP server. The precision API respects system time adjustments.
To confirm if a Windows 7 machine has the required update:
kernel32.dll version (should be 6.1.7601.18015 or later).
