There are compatibility issues between .NET Framework 4.5 or over and SDK 7.1. Most of NI Veristand user have to consider software configuration below. Model tools such as Simulink require a VC++ Compiler to build models for NI Veristand. And, the problem is Visual C++2010 Compiler under SDK 7.1 only works with .NET Framework 4.0. If either Veristand Model framework or Model Tool was upgraded, .NET Framework version would be upgraded automatically. So, this problem is solved with SDK Patch.
Depending on the version used the .NET might not be supported on VC++ compiler. Use the flow chart below to help determine the installation options available for your needs.
Note: SDK 7.1 patch download link is here (External Link : Microsoft Visual C++ 2010 Service Pack1 Compiler Update for the Windows SDK 7.1)
