An ePub is an open industry format known for its compatibility across e-readers and other devices, though accessing this file type does require an app or software to read. This file type is not a one-click reading experience such as a PDF or similar. View our ePub Guide to learn more. Once you purchase and then download your file from your confirmation email from us, you will not be able to immediately open and read it without one of these apps or services.
Note: Kindle readers can and should purchase ePub files to read on their Kindle devices or via the Kindle app. As of August 2022, Amazon no longer supports mobi files.

Resolving "GetSystemTimePreciseAsFileTime" Errors on Windows 7: A Complete Guide
Released in February 2013, this update was primarily aimed at improving DirectX 11.1 support, but it also brought several system API enhancements, including:
If you need the high precision provided by GetSystemTimePreciseAsFileTime , you may want to consider upgrading to Windows 8 or a later version of Windows.
The original Windows 7 kernel (NT 6.1) did not implement the necessary internal interfaces for exposing high-resolution UTC time via the Win32 API. Windows 8 (NT 6.2) introduced a major refactoring of kernel time management, including:
// To maintain precision without floating point math: // We calculate the seconds and remainder ticks separately. ULONGLONG seconds = elapsedTicks / s_frequency.QuadPart; ULONGLONG remainderTicks = elapsedTicks % s_frequency.QuadPart;
if (dyn_GetSystemTimePreciseAsFileTime != NULL) // Safe to call on Windows 7 (with KB3033929) dyn_GetSystemTimePreciseAsFileTime(&ft); else // Fallback to GetSystemTimeAsFileTime (millisecond granularity) GetSystemTimeAsFileTime(&ft);
