Hi
I have Installed cognos8.4

Jre is pointing to cognos jre.
jar file is copied from oracle to cognos. all the environment variables are set.

when i tried http://localhost:80/cognos8
Cognos Connection Screen splash for a sec and then i get page not found.

In IIS6.0
when I right click browse on cognos8 virtual directory it splashes for two seconds and page not found error

I am banging my head on this from last two days no solutions..
Pls let me know how to handle this

might sound daft, but have you started the cognos service? Can you test access to the content store via the configuration  tool?
