If the goal is to download OCI files on one server, and then access them from the OCI server to install, that may work - User Authentication Control can get weird with remote files, so often the easiest thing to do in UAC environments is to copy the OCI binary locally, spawn a cmd prompt as Administrator, and launch the .msi from the admin-level cmd prompt , as anything spawned from the cmd prompt will inherit the admin level / UAC free rights (in theory - there are some Active Directory driven UAC configs that may cause more pain)
