How do I resolve 'Dependent Assembly could not be found' in 64-bit version of 'PDFNet for .NET'?

Q: Today I tried out your 64-bit version of PDFNet for .NET by
downloading the trial and compiling your PdfViewSimple sample. I get
an exception that some DLL is missing:

Dependent Assembly:
could not be found. Please use sxstrace.exe for detailed diagnosis.
A: This error means that your machine is missing standard Microsoft VC
runtime. You could download & install VC 64-bit redistributable using
the following link:

  or search for "VC Redistributable" under Microsoft downloads.

Note: VC Redistributable is not required in 32-bit version of PDFNet
