Trying to download and install Spitfire Audio's Symphony and Related Libraries on non C: drive

Balbum

The spitfire audio settings allows me to change :

a) Default Content Path, and

b) VST2 Install Location,

HOWEVER IT WILL NOT ALLOW ME TO:

a) Change the VST3 Install Location, nor will it allow me to

b) Change the AAX Install Location

Now, if I understand correctly - I NO LONGER NEED TO USE VST2 or AAX versions of plugins but NEED TO USE A LARGER DRIVE than my C: drive to host the Spitfire Symphony and other large software sample libraries.

How do I get to a feasible solution?
