You lost me-What is the diff between running manually vs automatically?
I 'ran' the Fix-it tool, chose 'Detect Problems and Apply Fixes For me-Recommended,' it asked if I was having issues with installing/uninstalling, I chose uninstalling, it brought up a list of programs, including 'Not Listed' so I chose that then it asked for a Product Code and to press 'Next'-I could not get beyond that without a Product Code.
I 'ran' it again and this time chose 'Detect Problems and Let Me Select The Fixes To Apply,' it asked if I was having issues with installing/uninstalling, I chose uninstalling, it brought up a list of programs, including 'Not Listed' so I chose that again then it asked for a Product Code and to press 'Next'-I could not get beyond that again without a Product Code.
Is there anything you can click when you see the question about a Product Code? Any choices at all you can make? Is there a field where you can type something in?
Maybe try right click Defraggler, go to Properties and then check the available tabs for mention of a "Product code".
