So I've tried this from the web UI frontend using admin level credentials... the installation sits and spins for hours without doing anything. I cancelled the install and followed the directions here:

Deploy the agent manually to a Windows computer
It gets to a point where the install just hangs again. What would cause this? Are there any error logs generated by the installer that may tell me what is going on?
