Anyone having this issue as well on some W7 systems?

Error Code 16019

Connector update from 7.5.5.21061 to 7.5.7.21234 failed.   Error: Unable to verify Secure Endpoint's digital signature. Please update Windows..

Might be a root cert issue... since Win 7 isn't getting updates, it's not getting new root certs.
No new root cert, can't verify the signature on the new code that as signed with a cert based on a new root...
Really is time to retire that Win7 stuff...

Hello @JOVER ,
the Secure Endpoint Windows Connector OS compatibility page (https://www.cisco.com/c/en/us/support/docs/security/amp-endpoints/214847-amp-for-endpoints-windows-connector-os-c.html) shows the need of Microsoft KB5003228. It points to Microsoft how to update the endpoint before installing Secure Endpoint 7.5.7.
Greetings, Thorsten

which this is from 2021 that the doc references so most likely a newer cert/windows update that needs to get addressed before Win 7 can update to latest 7.5.x agent

I am seeing this on Servers 2016 and 2019 as well.
