Unless I've misinterpreted this article it should be possible.
Admittedly step 'N' isn't particularly clear, but I'm assuming they meant place the contents of everything unzipped in a folder called "portal" on the root folder of IIS (C:\inetpub\wwwroot\portal\). In any case I've tried that and creating a virtual folder within IIS called 'portal' with the files at wwwroot both complain that MainUI.html doesn't exist (and it doesn't! But I also can't locate that file on a Connection or Security Server - which leads me to believe it is generated from one of the .json files)
Has anyone been able to pull this off? Any suggestions as to where I've gone wrong?
