I'm following the 5 step installation process for YAF and I am at the point of browse to /install/default.aspx. When I do that it runs for about 20 seconds then gives me the error shown below. I know the default.aspx page is in the install folder. I am sure my website is pointing to the correct folder because I can open the SpamWords.xml file in my browser which is in the same install folder. Can anyone tell me why the install is crashing? I don't see the name of the file it can't find.

I was also getting this error from the web.config file: ""Cannot add duplicate collection entry of type 'add' with unique key attribute 'extension' set to '.axd'"" I commented out that line in the web.config file to get the website to run.

Server Error in '/' Application.

I think I need to fix the connection string in db.config. I will post a follow up later.

That fixed the problem. I had a bad connection string in db.config. Now the install wizard is working.
