Fusion 8.1.1 Installer

Hi,
I'm sorry if this question was already explained in this forum or have an too obvious answer:
I just downloaded the FREE version of Fusion 8.1.1.
Apparently, the installer does not allow me to choose any other drive to install Fusion other than C:/Program Files/... (the OS Primary active partition).
I do not want any software to be installed on C:/ other than OS related apps.
The previous Fusion 7 FREE versions allowed to be installed on any chosen drive.
Am I doing something wrong or is this the only available option for this installer?
Many thanks in advance.
Cheers.
