I'm using SugarCRM on-demand, I believe. I made it past that initial alert and it is now saying:
The package you are attempting to install does not conform to the policies established within the Sugar Open Cloud or by your system administrator.
Sugar Open Cloud customers must obtain a new package from the package provider that addresses the issues described below.
If you are running Sugar locally, you can relax your Module Loader restrictions to allow the package to be installed."
