Hi dear I installed a programe some days ago in my computer with a Product Key, now I uninstalled the program to reinstall it with different Product Key, but when I run the installation it dos not ask me for key and install the programe. I assume after uninstalling a programme, product key and other details will remain in my computer. My question is how can I remove Product Key and other details of the programe from my computer after uninstallation, in order to reinstall the programme with fresh product key and activation number. thanks for your help in advance
