How to install plug ins on another drive than C

I have a problem with the intallation of the Absolute 3 suite.
My Cubase is installed on my D drive that has plenty of space but, no matter what I do, the plug ins install themselves on my C drive, a 120 gigas SSD that has not enough free space left to accomodate the gigas of data of just Symphonic Orchestra, so far from enough to accomodate The Grand and Halion 6 (the three I need right now)
And there’s no way I can free enough space on my ssd just to have The Grand running…

I ain’t no IT technician but usually I’m able to make any program install itself on my D drive (games, other softwares etc…)

Help meeee please this is soft I need for work :frowning:
