PDFNet 5.7 .Net 4.5 Windows 8.1x64 crash - pdftron

Question

I've encountered a crash when using PDFNet 5.7 in a .Net 4.5 64 bit application running on Windows 8.1 The issue is only occurring in this scenario. .Net 3.5 works fine with Windows 8.1 and .Net 4.5 works fine on Windows 8.1 64-bit when run in 32 bit application.
The actual crash is (from EventLog):
Faulting application name: PdfNetDriver.exe, version: 1.0.0.0, time stamp: 0x543f4825
Faulting module name: KERNELBASE.dll, version: 6.3.9600.17055, time stamp: 0x532954fb

When the exception occurs - the exe dies straight away. No exceptions pop up. Nothing can be done. The program never makes it through the method that initializes the PDFNet component, eg.:
public static void SubMain()
{
// Initialize PDF
PDFNet.Initialize(LIC_KEY);
PDFNet.Terminate();
}
Any ideas?

PDFNet for .Net comes in four flavours, and each has a dependency on VC++ Redistributable
.Net 2.0 x86 : http://www.microsoft.com/en-us/download/details.aspx?id=29
.Net 2.0 x64 : http://www.microsoft.com/en-us/download/details.aspx?id=15336
.Net 4.0 x86 : http://www.microsoft.com/en-us/download/details.aspx?id=5555
.Net 4.0 x64 : http://www.microsoft.com/en-us/download/details.aspx?id=14632
So you say
PDFNet 5.7 in a .Net 4.5 64 bit application running on Windows 8.1
does not work
I don't think the PDFNet .Net 2.0 build will work in .Net 4.5, so make sure you are using .Net 4.0 version. Since it is 64 bit you can use either the 32 or 64 bit versions. You just need to ensure the VC++ redistributable is available.
You can check what a particular PDFNEt.dll is by checking the details tab, in the properties menu, in Windows Explorer.
Make sure to expand the filename column as if it is 64bit that will be indicated at the end of the line.
