I am not sure if this is the right place to ask this question.
I was trying to apply the latest KB4536989 patch to my Exchange 2010 SP3 server which has hub transport, mail server and edge transport in one place.
When I tried to apply it, it came back with the following error.
I reran it again by using "Run as Admin" but the same result.
Does anyone encounter the same error?
Try running from elevated command prompt:
msiexec /update Exchange2010-KB4536989-x64-en.msp
I encountered the same issue and so far, running from command prompt is allowing it to proceed as expected.
According to your description, I found a similar thread "Exchange 2010 SP3 Apply KB4536989 Error Ended Prematurely", you could refer to Vera Shen or others' replies. Hope it helpful to you :)
