This is outside most people's knowledge within the "Licensing and Install" community, so I suggest that you raise a service request through Supportnet.
However, I've taken a quick look and located a technote talking about a similar message when using Pro/Engineer Wildfire 5. Take a look at: https://supportnet.mentor.com/portal?do=reference.technote&id=MG537725
I also see that the release notes for FloEFD for Creo 14.2 say that Сreo Parametric v3.0 (recommended datecode M020) is supported, whereas you are using datecode M050. This might be significant, but I suspect that the protk.dat changes above will make more difference.
I hope that helps.
thankyou for your reply, I will check tech note and try with M020 release ..... and will give response
