Hi, so I'm new the the forums and also Defraggler. I recently uploaded the program on my IBM ThinkPad model computer and for some reason, defrag as well as analysis options do not work. Instead a message appears "Closes...due to inconvenience". After, the window promptly closes. I am not quite sure if my other program DisKeeper Lite is interfering with the program. I hope this helps and I thank you for your service and help.
