[BUG] FUSION_PROFILE_DIR does not work

System
Fusion 7.7, Win7 x64 Sp1

Steps to reproduce
Follow the documentation on p. 281

Expected behavior
Profile directory at FUSION_PROFILE_DIR is created / used

Given behavior
Default profile directory is still set in the path maps.

EDIT: In case it is not obvious, this is also true for the other env vars related to the profile.

This still applies to 7.7.1.
Can someone verify with Fusion Studio?
