Agent deployment from ChangeAuditor Client to remote servers fails with the error "An unknown failure during deployment occurred. If this is the first attempt..".
Investigation of the installation logs found under C:\Windows\Temp\ on the Agent server reveals an error similar to the following:
"MSI (s) (38:70) [10:36:31:398]: Product: Quest ChangeAuditor Agent 6 (x64) -- Quest ChangeAuditor Agent 6 (x64) requires Microsoft Core XML Services (MSXML) 6.0 to be installed."
Install the x64 version of the Microsoft XML Parser (MSXML) 6.0 on the Agent server.
