On my Win 7 laptop I have had problems getting NIS to run. I have finally managed to run Norton Removal Tool but the promised reinstallation did not start. I logged in to my Norton account which is advising me that "NIS has no remaining install."  My account expires next year and covers 3 pcs which include the problem machine and this one which is running Win 8.1 and is working OK (so far). Please help or I fear that I will have to reformat the Win 7 machine with all the hassle that that entails. I need the Win 7 machine to run a daily task that cannot be performed on Win 8.1.

Thanks bkk-bkk
