Your application requires the Visual C++ 2008 Redistributable (x64) with a specific version.
On Windows 8 x64, the processorArchitecture="amd64" tag is critical. An x86 manifest will fail on an x64 OS unless the application is running under WOW64 (Windows 32-bit on Windows 64-bit). sxsi x64 windows 8

While SxS existed in Vista and Windows 7, Windows 8 introduced critical refinements, particularly for x64 systems. The most notable was the aggressive reduction of the WinSxS folder’s physical size on disk. Prior to Windows 8, the WinSxS directory appeared deceptively large because it used hard links to store single copies of files referenced in multiple locations. Windows 8 introduced and a more intelligent servicing stack. The dism.exe command-line tool gained the ability to perform a "base reset" (e.g., DISM /Online /Cleanup-Image /StartComponentCleanup ), which permanently removed superseded versions of assemblies after a servicing operation. For system administrators on x64 servers and workstations, this was revolutionary; it meant that the SxS store no longer grew indefinitely with every Windows Update, conserving precious disk space and reducing I/O overhead.

Applications compiled with Visual Studio 2005, 2008, or 2010 rely on manifests. These are XML files embedded in the EXE or stored externally. They list dependencies, such as: Prior to Windows 8, the WinSxS directory appeared
In the 64-bit architecture of Windows 8, managing these components is essential for system stability, backward compatibility, and external storage performance. Understanding Windows Side-by-Side (SxS) on Windows 8 x64
