I have followed all the installation instructions from here: http://www.sitefinitywatch.com/blog/09-05-04/Bullet_Proof_Guide_to_Installing_Sitefinity_3_x.aspx but after Installation, and configuring all settings, I just get a http 404 error. OS is Windows 7 64 bit, SQL Server install is SQL 2005 as well as SQL Express in a VS 2008 environment. Any clues what's going wrong?

I removed dnn and main page now appears. Dave Penny Reply Home / Developer Network / Forums / Sitefinity 3.x: Set-up & Installation > Installation gives 404 error
