I installed Norton with E: as the standard partition that also contained all user data(some tweaks required). Norton installed correctly in C:/, but all folders suppossed to be in ProgrammData were found in E:/. After every reboot Norton quit with an error 8506, 421. furthermore the error log (also found in E:/) said it couldn’t find a registry entry which has the same name as one of the folders in E:/ProgrammData/Norton and the format {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}. i manually copied all files from E:/ to C:/ , i hope this will solve the problem
