Hello and welcome to the forum.
Did you install the Sounds Library too?
Try running the standalone Miroslav Philharmonik 2 ("MP2") program first, configure its MIDI input and audio output. Make sure that you have selected the library path in MP2's Preference Settings.
Also check out the MP2 User Manual that was installed when you installed the software or get it from the IKPM (the IK Product Manager).
As for FL Studio, you would load MP2 in the same way as you load any other (multi-output) instrument plug-in. I do not know the details. But, is FL Studio scanning the folder where the MP2 plug-in was installed?
