Once you have the package created and deployed, you will come across this problem.

Sep client will be installed in the ...\Program Files\Symantec\Symantec AntiVirus Folder and not  ....\Program Files\Symantec\Symantec Endpoint Protection no matter if you put in a destination folder or not.  Looks like a complete un-install of SAV then deploy Sep, unless there is a better solution.

if its an upgrade then it will be under 

Program Files\Symantec\Symantec AntiVirus Folder

if its a fresh install it will be under

Program Files\Symantec\Symantec Endpoint Protection

may be thats why you find symantec antivirus folder 

Yes you are correct but can this not be fixed by Symantec?

Rafeeq, the setting to remove previous logs, policies, etc. worked.  I didn't think it would also remove the program, so I had not selected that option.

por997, you are correct, although SEP uninstalled SAV, SEP got installed into the C:\Program Files\Symantec AntiVirus folder!  Looks like I'll have to continue my standard practice of using a .VBS wrapper script that will uninstall an old version, clean up the folders, then install the new version.

if you could share that script, i'm sure will help others :) 

Cheers Guys, that wil be a good help also!  Thank you very much.

Sorry, I don't mean to lead anybody on.  I have yet to try and write a script and test to see if it will uninstall SAV 10.1.6.6000, even though there's a password, and see if it will not require a reboot.

I did however find an old script that was used to uninstall SAV 8 in preparation to install SAV 10.  I noticed they were two different scripts.  So I'm guessing there was a reboot between the uninstall and install.  Here's that SAV 8 uninstall script.  It used the msiexec.exe /X command to uninstall a package.

Const HKEY_LOCAL_MACHINE = &H80000002
Set WshShell = WScript.CreateObject( "WScript.Shell" )
cmdLine = "MsiExec.exe /X{0EFC6259-3AD8-4CD2-BC57-D4937AF5CC0E} /qb-!"
strKeyPath = "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon"
Set objReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\default:StdRegProv")
If Err = 0 Then
    setReturn = objReg.SetStringValue(HKEY_LOCAL_MACHINE, strKeyPath, "DefaultUserName", "")
    setReturn = objReg.SetStringValue(HKEY_LOCAL_MACHINE, strKeyPath, "AltDefaultUserName", "")
Else
    Err.Clear
End If
For Each objSoftware in GetObject("winmgmts:").InstancesOf ("Win32_Product")
    If (LCASE(objSoftware.Name) = "symantec antivirus client") And (objSoftware.Version > "8") And    (objSoftware.Version < "9")Then
       WshShell.Run(cmdLine)
    End If
