I have recently installed 7.1 but I have noticed that the previous version 7.0 is also there. It is not in add remove so how else would I uninstall it. Should the newer versionnot just have overwitten the older?
When you say that the previous version is also there, have you tried to run the previous version? It may only be the shortcuts to it that remain. Double click on the program name for it and see what program runs - it could well be version 7.1.
