I have copied my ppro folder in W7RC and installed the last version of PP with administrative rights and it seems to function as supposed (but I have not tested all functions yet). very good news! One thing seems to function as supposed: launching Ppro during the boot of Windows. I have tried to give administrative rights to the main exe file and to the shorcut that is in the Start Menu but it continues to ask me the authorization when I try to start PP manually (and it does not start it automatically).
