I installed the SP2 for Vista yesterday. After that i had some problems with my internet connection and i decided to make a "repair installation" of ESS. But i received an error message that i don´t have the righty to modify the programm folder and the registry keys of ESS. So i couldn´t neither repair nor deinstall ESS. But i´m logged in als admin. After canceling, ESS told me that the real-time file protection could not get enabled. I switched to the setup menu to enable the file protection and again an error message that i don´t have the rights to modify the settings. Now i switched back to SP1 and everything is fine. I can deinstall and repair and modify the settings. So i tried to deinstall ESS before i install SP2. Then i installed ESS after installing SP2, restart, and there was the same problem. I really don´know what to do. I installed everything on my girlfriends laptop as well and there everything is fine.
