"Failed Installation" errors with Application Manager 2.3.3

[General Stalin]

I have just installed and Registered Pro Tools 12 which as you all know requires Installation of Avid Application Manager.

Is any one else having these issues? I have been searching Google all morning and this forum and can't find people getting these same errors as me:

Try to install XPand II and get "Failed Installation: Xpand II install failed. ack."

When I try and install a different plugin I get the error "Failed Install: ______ install failed. The installation of another program is in progress."

When I go back to XPand II and click install again I get the error "Failed Install: XPand II install failed. This installation already started"

I've already tried completely uninstalling Avid Pro Tools and all components and reinstalling and getting the exact same issues. This application manager tool is currently hindering my Pro Tools usage as it's preventing me from installing plugins and updates.
