Path to set up ENOVIA 2015x with latest FP ( i.e. FP1524 )

Hi

Can any one confirm me, what’s the path to set up ENOVIA 2015x with latest FP ( i.e.  FP1524 )

 ENOVIA R2015x -->> ENOVIA R2015x+FP1524  ( 2 step process)

 Or

ENOVIA R2015x -->>  ENOVIA R2015x+FP1517  -->>  ENOVIA R2015x+FP1524   ( 3 step process)

 

The vanilla environment I need to set up as per OOB components, so if any one on latest FP, can guide me, is it two step process, or it's a three step process.

 

Regards

Mayank
