Microsoft XNA Framework 4.0 Setup error (-2147024703)

When you install the Microsoft XNA Framework 4.0 (xnafx40_redist.msi) package, the setup may encounter the following error:

Module C:\Program Files (x86)\Common Files\Microsoft Shared\XNA\Framework\Shared\xnavisualizer.dll failed to register. HRESULT -2147024703. Contact your support personnel.

Cause

The error -2147024703 (hex: 0x800700C1) means ERROR_BAD_EXE_FORMAT (the file is not a valid Win32 application).

To register xnavisualizer.dll, the 32-bit version of msvcr100.dll should be present in the C:\Windows\SysWOW64 directory. If the SysWOW64 directory has the corrupt or the 64-bit version of msvcr100.dll, this error occurs.

Resolution

Download msvcr100.dll (32-bit, zipped), unzip, and copy the DLL file to Windows\SysWOW64. Overwrite existing file if prompted.
