Hi John,

What error is MsiInstaller giving in the Windows Application Event logs?

Can you find the MSI log and see what errors are in there?

After the uninstall attempt,look in %TEMP% for the log.

Hi,

Download windows cleanup utility & remove Symatec Endpoint protection.MSI file.

Hello,

Are you able to manually uninstall SEP from the machine? How many machines are you facing this issue on?

Are there any GPO policies applied? Hope you are uninstalling the softwares with proper rights.

Try considering this Option as well -

Hope that helps!!

Try using an uninstaller if cleanwipe has failed.

Some uninstallers liks "Revo uninstaller" has a hunter mode.  You use that to target the uninstall you want and it should be able to remove the remaining files/folders and registry keys left over by a failed/botched install/uninstall.

My MSI Log After an unsuccessful attempt to remove

Here is the point of failure:

stopProtectedService: Attempting to stop SmcService
stopProtectedService: Unloading BASH driver...
stopProtectedService: Failed to unload BASH with HRESULT=0x80070005

You can get around that by disabling the BASH service, rebooting, and then performing the uninstall again.

Disable BASH driver (BHDrvx86/64) via command line:

1.  Open Command Prompt

For x86 type: sc config BHDrvx86 start= disabled

For x64 type: sc config BHDrvx64 start= disabled

2.  Reboot the machine for the change to take affect

3.  Re-run the install/uninstall

 Let me know if that succeeds!  &: )

Hi John,

When time allows, please do update this thread with news of whether the procedure above worked on your SEP client.
