Installing 2016, but the client (the business owner) struggled supplying a username/pw combination that would work to get us past the Sage Integration Engine service setup. Ended up using Administrator (without the domain\usename). The install did not fully complete (got ALL the way, almost to the end); then Setup failed to create the service. If I re-install, I don't get to that screen again. Once we get a login that we know works, can I re-install, or will I have to uninstall and start from scratch? @SageCRM
