Hmm... I have CS5 (home video so no income to pay for monthly CC) and I do not have Quicktime installed... and have never had your problem
Only other thing I can suggest is...
Adobe/Jive have a BAD title for the SEARCH THIS FORUM function
Go to http://forums.adobe.com/community/premiere and, in the area just under Ask a Question, type in
ImporterQuickTime.prm
You may now read previous discussions on this subject... be sure to click the See More Results at the bottom of the initial, short list if the initial list does not answer your question
Thanks again John for the help,
As it turns out the problem was the display drivers (kinda-sorta). The clue was the stall at ImporterQuickTime.prm followed by the error screen referring to the inability to find a suitable driver. A long time ago I tested the JAWS software so I could have a better understanding of what a vision impaired person would hear when scanning an accessible website. I never bothered to remove this software. When I checked my device drivers on Windows I discovered that I had a virtual mirror driver by Freedom Scientific (The creators of JAWS). After removing the software and the driver I was able to open Premiere Pro CC normally, even after repeated tests and reboots of my computer. It has worked flawlessly every time.
As far as my previous success (and subsequent failure), I'm still clueless as to why that worked, albeit temporarily.
This is a fluke cause of failure and the fix probably won't help anyone else.
Regards,
Robert
