I needed to install Trillian on an old computer for some work. When I installed it, it comes up with an identity of a previous user from long ago when Trillian was previously installed on this computer.
So I ran Add/Delete Programs. Then ccleaner to clean up any junk.
After re-installing Trillian, it still came up with the identity and contact lists of the previous installation. And there is no apparent way to get rid of this information.
How do you cleanly remove Trillian so it does not keep preserving the old info?
