Premiere installation failed, too.
After cancelling, AAM shows Premiere installed, but there is no (visible) Premiere.app or Folder on /applications.
Starting my Creative Cloud installation, member/no trail, with PS, AE , Premiere... PS 6, AE works fine
System requirements should be ok: MacBook Pro (early 2008) OSX 10.6.8 / Intel Dual Core 2,5 GHz / 4GB RAM/
No Problems with CS 5.5
