I understand you cannot confirm the cause of these single issues without further information.
But in general, there are often errors, which do not make sense.
I deploy SW to a group of computers, all UP, all in local office, online via LAN cable, so no connection problems.
One clients installs fine, the other fails. Reason: "Either you havent provided the silent switches or the silent switches are incorrect"
I mean, seriously, the error cannot be correct? If it was, the software could not be installed on any other clients.
Same with errors like "Error occurred while fetching the package path url".
It does not make sense and so I cannot understand (on my own - without the support), why this happened?
Most times it is "ok" after 1-2 retries (and I did NOT change the "silent switches" for example).
I just want to say: The errors DTC reports during a failed installation are not correct.
