[ICOM] Icom Windows Cloning software questions

[r miles]

I have the older  Icom CD to program the IC T7H. I shared it with my 
late friend W9RVR who had an IC W32. The software did several radios. I 
now have an Icom IC T90A from my late uncle. I want to program it  for 
two of my grandaughters  going off to college this fall. They are hams & 
want to use it in a major city where they will be.
My 1st question is: will that software  work on th IC T90A too?
My second  question: the  cable has a 9 pin connector for a serial port 
on the PC. My new laptop only  has USB ports. Can I just get an adapter 
serial to USB cable or plug  to insert  in the cable going from HT to PC 
if the software will work?
I  hope my questions are clear enough to follow.
