I have Dell Studio 1555 laptop and have windows 7 Home Premium x64bit installed. I have tried lot of times to install SEP 11.0.4, but all the times i'm getting the below error. "The wizard was interrupted before Symantec Endpoint Protection could be completely installed. Your system has not been modified.To complete installation at another time, please run setup again." I searched in the net for its solution, I got that first to install LUSETUP.EXE, then reboot and then Install SEP11 by running Setup.exe. But still then i can't able to install. Still i'm getting the above error. Can someone help me out on this. Thanks Pragnya
