Why does my FME Server Web Interface not show a login button

This issue is also a symptom of a bad install of FME Server.

In FME 2017.0 I've found that if you use the 'Custom\\Distributed' install option to install FME Server to allow you to set a specific account to run the service with in the installer config for example. Then when installing you define a shared resource directory somewhere on the machine or your network where that user does not have permissions, you'll end up with a bad install (no warnings or errors).

Once installed, if you access the web interface you'll find that you can't login with the admin credentials and the interface's login button will be missing (not completely, just obscured). Further investigation for me revealed that the only services running were the web application service and the database, the core hadn't started. Numerous reboots and some hacking later I reinstalled, this time with the Express installer, again everything was fine till I got to defining the network share and after issuing a UNC and clicking next the installer complained that we didn't have permissions to this network share path. Clearly that was the issue before but this time the installer checked and flagged up the issue. We granted the correct permissions and continued... When install was finished, everything started and ran fine. Safe are aware (C128344), but thought it worth adding to this thread given that its a different type of permissions issue that caused the same problem.
