Errors in executing first RoR app - reg.

There is nothing wrong in controller or view..... but something problem in installation..... what version of Instant Rails you are using..... also try to use ruby console window from Instant rails to create apps...that adds all paths correctly......

Also start server using Instant Rails ... click on "I" ... "rails application" -> "manage rails applications"..then choose your applicaton and start server....... good luck in exploring RoR
