Hi Mauro,

I performed the same test with our Windows Server 2012 installation and
was able to recreate the issue.

The ReportBuilder REST Server utilizes TClientDataset to organize the
directory structure before converting to JSON and transferring data. On
your Win 8 machine with Delphi, the midas.dll is likely installed which
is necessary for the use of TClientDataset. Your server (as ours) does not.

To work around the issue, you can either add "MidasLib" to the uses
clause of the RB REST Server demo and rebuild or you can add the
midas.dll to your WINSYS directory of your Windows Server machine.

For a future release we will research removing this requirement.
