open services.msc

stop Symantec Settings Manager

Symantec Event Manager

and sygate security services.

install the pritner and enable those again.

Right click the SEP icon in the task tray and select "Disable Symantec Endpoint Protection"

Well, neither of these above actions worked.   What services correspond to sygate security services?  This is the firewall, but can only find Symantec Settings Manager and Symantec Event Manager.

Tried "Disable Symantec Endpoint Protection" first but still get the message from the installer.

Attached are the services that are running re: SEP

hi,

Check this firewall showing in your system tray

Sygate Personal Firewall
In the bottom right corner of the system tray you will see the icon showing up/down arrows for your Sygate Firewall.
    * Right-click on that-> Choose "Exit Firewall".
    * A message will pop up to notify you about disabling the protection. Select "Yes."
    * The icon in the system tray will now disappear to indicate that you have successfully disabled the Sygate Personal Firewall Guard

That's what's weird as there is no Sygate Firewall that I can see, only Symantec SEP v1  running. There's no icon in the Systray for Sygate.

try disabling the driver and check if you can install!

Hi,

First you can uninstall sep client and install printer driver..

Is the printer install not working? Have you tried it? Or will it not let you proceed until fw is disabled?

Hi,

You can try with stop the symantec services and then try to install printer driver.

I hope it will be work.

Well, guys, NONE of your solutiones worked....  

I tried running the install in Safe mode with networking and that just hangs.

Ashish, uninstalling SEP is NOT, repeat NOT a solution. Symantec should have a real solution to this problem. I would only do this as a last resort. Symantec's SEP should have a mechanism to allow ALL legitimate S/W to be installed. 

 In my initial post I referenced the Sygate Security Agent. From what I've dug into, Symantec's SMC.exe is the firewall client. Is this correct???

Are any people in these communities reps from Symantec???   Thanks for your input, but I also need to get with HP to resolve their issue with the printer install..
