I've tried installing and re-installing and umpteen Live Chat sessions. I've tried calling Adobe Tech. Support. "Current wait time is between 57 minutes and 1 hour."
I've followed all of their instructions but still, bizarrely, when I click the "FrameMaker 12" option under the installed ATCS 5 folder (Start > All Applications), what opens is "FrameMaker XML Author 12," which cannot open .fm files and prompts me to "download the full program."
The last Live Chat person told me to uninstall ATCS 4, and then, when I logged in to the Adobe site again, I could click "License this Software."
No such link appeared. And now, we are stuck without a mission-cirtical software package, days before a release.
Unbelievable.
