You chose:
"I am currently using ROOTS V and want to install
UFT. I don't care about the directory name for my data and programs and
I want to shift immediately to use UFT without the ability to go back to
use ROOTS V."
This is the easiest way of all; all you do is choose the "update a previous
version" when you install UFT. The install program will search for and
find your ROOTS V installation and ask you if this is the one you want
to update. Say yes and you're home free!
You should note that your new UFT program will be in the directory
where you had ROOTS V installed, and that the ROOTS V program will have
been deleted.
