I already have another anti-virus application installed on my computer. Before installing Sophos, make sure that you have already uninstalled all other anti-virus programs (such as Norton Anti-Virus, Mc Afee Virus Scan, etc.) from your computer.If you do not do so, Sophos may fail to install or not run properly.
Sophos returns the error “25011: Sophos Auto Update could not read updating settings from [source].Contact your support personnel.” •Sophos appears to install successfully but returns the error “You do not have sufficient privileges to run the Sophos Anti-Virus main application.You are not a member of one of the Sophos groups…” •I am having problems uninstalling Sophos from my computer The Sophos installer files fail to extract properly Before the actual installation process begins, Sophos will attempt to extract and copy all of the installation files into your C:\Windows\Temp folder.Click OK to continue installation.” If Sophos returns the above error message during installation or returns an error that refers to “sauconf.xml” the Sophos Auto Updater is not pointing to the appropriate autoupdate servers.Some anti-spyware programs may prevent you from extracting these files properly.
Please temporarily disable any anti-spyware programs on your computer.
