Why do I Receive a Microsoft Visual C++ Runtime Library Error when Executing a TestStand IVI Step on a 64-bit Operating System?Primary Software: Primary Software Version: 4.0 Primary Software Fixed Version: N/A Secondary Software: Instrument Drivers/IVI>>IVI Engine Package
Problem: I am running TestStand 4.2.1 or previous on a 64-bit operating system. When attempting to execute an IVI step, I receive the error below. Upon clicking OK, TestStand proceeds to crash. Why am I experiencing this problem and how can I resolve it?  Solution: TestStand reads the export information of DLLs located in the <ProgramFiles>\IVI Foundation directory when first executing an IVI step. On 64-bit operating systems, some NI drivers install 64-bit DLLs to the IVI Foundation directory. TestStand 4.2.1 and previous versions incorrectly read the header information of 64-bit DLLs which results in an unhandled exception that leads to the Microsoft Visual C++ Runtime Library error displayed in the Problem section of this KnowledgeBase. If you are experiencing this behavior on your 64-bit operating system, please contact National Instruments Support.
