Hi,
Well, there can be remnants left from some software uninstalls. However, if you don't see any problems, then don't worry about fixing something that is not broken.
If you need help with that software issue, then explain what it is and the problems you have with it and someone might be able to help you. They also might advise you not to load that program, so if you have a need to know, then explain away.
Post back with questions/concerns.
