Yea, I worried over that too but I rolled the dice and simply said OK to that dialog and it didn't screw up anything on my system.  Everything running hot straight and normal.

hoochie coo

FWIW, I choose NOT to install the Pace Interlok driver and it seems to be working fine without it.
 
I searched the internet and could find a lot of old refrences to the Pace Interlok Driver and they all refred back to a dead page at the old iLok pages.
 
I wrote an email to Synthogy hoping to get a final explanation.
 
I was very afraid to screw up my iLok. The new iLok license manager stuff is working so well... I didn't want to go backwards and get messed up.
 
best regards,
