Failed loading extension CreditCardProcessing
Failed Loading extension CreditCardProcessing. Error 1114 - Adynamic link library (DLL) initialization routine failed.
This error occurs on Windows 10 systems that do not have .NET 3.5 installed, which is a requirement for POSLink, which is inside CreditCardProcessing.dll.
This page should explain how to install .NET 3.5 on the system; the error should go away after that.
