SEPM failed upgrade from 12.1.5 to latest version

Good Day,

I tried to upgrade my SEPM server to 12.1.6 mp4, but encountered error even before the upgrade process completed.

Has anyone encountered this error? On the event logs I saw this error

The Apache service named  reported the following error:
>>> (20024)The given path is misformatted or contained invalid characters: AH00532: Invalid config file path C:\\Program Files (x86)\\Symantec\\Symantec Endpoint Protection Manager\\apache\\conf\\httpd.conf  

Thank you and Regards
