16.019 error

[joshuaer]

Hello,

I have a couple of Windows 10 clients that are failing the update from 7.5.3 to 7.5.7.21234 with the error 

16.019 Unable to verify Secure Endpoint's digital signature. Please update Windows.

Can anyone point me in the right direction?

Thank you

If you check the Release Notes for 7.5.7 it shows the requirements.

The connector installer in version 7.5.7 and later will now check for certain
Windows patch levels to make sure computers are up to date before proceeding
with the install:
• Windows 7 - KB5003228
• Windows 8.1 - KB5011564
• Windows 10 version 21H1 - KB5011487
• Windows 10 version 21H2 - KB5011487
• Windows 11 - KB5011493
• Windows Server 2008 R2 - KB5011552
• Windows Server 2012 - KB5011535
• Windows Server 2012 R2 - KB5011564
• Windows Server 2016 (Desktop & Server Core) - KB5011495
• Windows Server 2019 (Desktop & Server Core) - KB5011503
• Windows Server 2022 - KB5011497

Hope this helps,

In my experience, as long as windows update is up to 9/30/2021, amp 8.1.3 will install.
