How to register .Net 4.5.1 with IIS8 on windows 10

Dism would be the best way to do this:

Dism /online /Disable-Feature /FeatureName:WCF-HTTP-Activation45
Dism /online /Enable-Feature /FeatureName:WCF-HTTP-Activation45

Use the /all switch when enabling to enable all parent features.

The ftd2xx header has a lot of Windows types in it so you need to include windows.h before including the ftdi header.

The .lib file is a DLL link library which provides the linker information required to make use of the DLL at runtime. The following compiles and runs using g++:

#include <windows.h>
#include <stdio.h>
#include <ftd2xx.h>
int main(int argc, char *argv[])
{
    DWORD version = 0;
    FT_STATUS status = FT_GetLibraryVersion(&version);
    printf("version %ld\n", version);
    return (status == FT_OK) ? 0 : 1;
}

Compiled using:

g++ -Wall -Idriver -o check.exe check.cpp driver/i386/ftd2xx.lib

where the driver folder contains the distributed FTDI windows driver package. The -lftd2xx will have the linker searching for something called libftd2xx.a so just explicitly provide the .lib filename.
