Cannot Install Delphinus

[cs-ftlabs]

I am trying to install Delphinus to use when installing LoggerPro for Delphi. However, everytime I run the Delphinus WebSetup application, whether by compiling or through the .zip file found online, I get this error in the log:

Downloading Delphinus

Have you started the setup with administrative privileges?
The setup does not enforce it atm (should add a manifest for it) and Program Files (x86) needs it.
