featureworks command execution failed

problem:

If I open a step file or open such a file in SW, and I want to do the featureworks , I get an error because I do not have the license. So far still the right because i don't have that license.

but then I get to see 2 screens and is solidworks is out .

I understand that I have no license and can't run it,, but it is very troublesome if every time solidworks falls out.

This week I installed SW 15th, may have to deal with it that?

Who can help me ?
