Jeff, via an email from Adobe Stacy Morrell, I was put in touch with the Adobe help desk using Skype. In the review of my problem, I was informed of two important facts since I am using the High Sierra operating system on my MacBook Pro . The first is that Adobe Premiere Pro CS 5.5 will not function under the MacOS High Sierra. I would need to move to Adobe CS 6. I was offered the opportunity to purchase CS 6 but declined since the cost is more than moving to Final Cut Pro. Secondly and more important, Adobe Premier Pro CS 5.5 can be dragged to the trash under Mac OS High Sierra to remove it from my applications. This is welcome news. While I appreciate your technical instructions for rectifying my problem, if reformatting my HD was the only option, it would have created the laborious process of totally rebuilding my application file with over 100 applications. Thus, I was ready to live with the 2.0+ GB of unusable space that the Adobe CS 5.5 and related applications occupied until a future technical reason to rebuild the HD arose. Thanks for you help, ChetGolfer
