SEPprep is an unsupported tool that is designed to uninstall any competitive or Norton products automatically. SEPprep can also launch another application before or after removing products—such as a new product installer—automatically and silently.
SEPprep works on all client-supported Windows operating systems (both 32-bit and 64-bit). There are two different binaries: one for 32-bit computers and one for 64-bit computers.
You can download SEPprep from the Attachments link.
The SEPprep.ini configuration file has a number of options that control how the SEPprep tool works. This configuration file is required for SEPprep.exe and SEPprep64.exe to function, and works much like any other traditional .ini file.
The configuration file is divided into three sections: ([Settings], [UninstallPaths], [ProductNames]).
Within the sections are configurable options/features of this tool. The .ini file and its configured values are the key to its functionality.
This section is the first section in the file. All the items in this section of the .ini file control how the SEPprep tool runs.
RunAfterRemoval=reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce /v "Install SEP 11" /t REG_SZ /d "C:\SEPInst\SEPsetup.exe
RunAfterRemoval=cmd /c "md C:\SEPInst"
RunAfterRemoval=cmd /c "xcopy *.* C:\SEPInst /e /y"
RunAfterRemoval=shutdown -r -t 30 -f
Use this section to add the registry path for uninstall strings. This is mainly for internal use and likely will not need to be modified.
It currently only has one item listed but more items can be listed if needed.
This section lists the name of any product to uninstall. The SEPprep tool will search through the Add/Remove Programs for any product whose name matches part of or all of the strings listed here.
The tool will go through this list in the order listed.
Note: The tool will match even a part of the name specified.
You can add SEPprep to a client installation package so that the installer removes competitive or Norton products prior to deployment.
Add SEPprep to a SEP client package on the Symantec Endpoint Protection Manager (SEPM) computer to enable use of the Find Unmanaged Computers wizard.
Note: This will also affect the AutoUpgrade feature of the clients as they also use these files to upgrade themselves to a later version.
SEPprep works on all client-supported Windows operating systems (both 32-bit and 64-bit).
