I did some checking on my system.
One out of three uninstalls has proven to leave some of the Circle Dock Files behind.
I had to Uninstall the program (to get the error). This did indeed uninstall some stuff.
I then had to go into the C Drive (C:/) and then to the "Program Files" (C:/Program Files)
Then delete the "CircleDock" Folder.
I also had to go into the "AppData" Folder and then to the "Local" Folder, and find and delete the "CircleDock" Folder there as well.
Once this was done I also deleted The Desktop Icon, checked to make sure that there was not any shortcuts in my "Startup" File, and deleted the shortcuts in the "All Programs" Folder.
I restarted me system, and went to Control Panel, and check the uninstall/Install programs window and found that the program had been removed.
I know that this version of Circle Dock also makes a registry entry, but I am unsure of where and what, and I never advise anyone to make a systems registry change lightly.
Since I am unaware of your Operating system (ie. Windows XP, Vista, & 7) and whether you are 32 or 64 bit, I am sorry I can not give somewhat clearer directions.
I hope this helps.
