I have windows 2008 - 64 bit and IIS7.5 , I can't use web sites under Classic Application pool. if I set Classic application pool, site shows error 404.17 , and try to use static handler for it's content.
If I use integrated application pool then some of my sites that use custom http module in their web.config dont work correctly. How can I use classic application pool?
UPDATE: if I set Enable 32-bit ... to true , classic application pool works
