In FlexSim 2016 Update 1, we updated to use Microsoft's new API enhancements for Windows that correctly and securely load external libraries.

In order for these API enhancements to work, you need to install a critical Windows security update (KB2533623).

You can download it here: https://support.microsoft.com/en-us/kb/2533623

Once you install that update, FlexSim will correctly load and connect to the module dlls.

Look at Phil Bobo's response in this post:

It has to do with how Windows load external libraries. (Modules like Process flow.) See the information on Phil Bobo's answer and install the update he links to his answer.
