title: Server Error- Could not load file or assembly 'log4net, Version=1.2.10.0'
body: <p>I am trying to generate a crystal report on a website that i created using visual studio 2012. I installed the Support Pack 8 Executable from this site: <a href="http://scn.sap.com/docs/DOC-7824" rel="nofollow">http://scn.sap.com/docs/DOC-7824</a> and integrted Crysital reports with my visual studio. I am able to generate the report on my computer, but when i moved my website to a different server I get an error. Initially i had errors about different .dll's missing, but after adding them it fixed the problem. I could not however get passed this one error:</p>
  
  <blockquote>
