Hi Sean Fulmer,
I am sorry for your negative experience.
Sitefinity is just an ASP.NET web site, and it can be deployed as any such web site. Please go to your Client.NET downloads section and download the blank project .zip archive for the .net version you use. Extract it somewhere on your file system (in an empty directory). Then go to IIS, add a new application pointing to the directory you just created. Remove the newsletter module, and finally go browse the created web site.
We are open to suggestions for improvement (as we are working on such) about the installation process. Any ideas would be welcome.
All the best,
the Telerik team
