CC Feature: denying installation of font files

For years now I've been using a program called AMP Font Viewer. It temporarily installs fonts onto the operating system upon request, and removes them upon quitting the program.

It is super beneficial when you work on multiple projects with various typefaces, because the program allow the operating system to stay clean of project font files, keeping programs' loading time to a minimum, in a clean operating environment.

Before CC, this program worked perfectly while Adobe's programs were running.

CC, however, is preventing this program from running properly. When attempting to use AMP Font Viewer, the mouse cursor becomes a spinning loading icon, AMP Font Viewer goes ghostly white, and is unable to perform its job.

To regain the control of installing temporary font files, I must kill all Adobe apps, i.e. Creative Cloud Client, Dreamweaver, Photoshop, etc. (but not necessarily background services).

For me this issue is a major setback and an unpleasant surprise.

I urge Adobe to avoid from locking up resources that users (alongside with the system) may need, and keep them available for other uses too.
