Symantec not updating

I have reinstalled both manager and client, I have searched this forum and Google but have found nothing that helps!

Other details, such as policy updates, enable/disable features, etc all work from the server to the client.

:-) Today, I uninstalled the manager software and the client software from the server.

If you click start then run and type on one of the clients will the client download the definitions?

I have Windows 7 Home Premium and got the upgrade offer to Windows 10.

I downloaded the OS and when it started installing, it reaches a point and gives an error message saying that Symantec Endpoint Portection needs to be uninstalled.

I think the problem might be that the client package was configured to be unmanaged.

"Download Live Update Content" shows that Live Update starts, checks for updates and does/does not download them as appropriate. I haven't tried to download the definitions on any of the clients themselves as it kind of defeats the object of having a managed solution!
