asp.net wont start - no code involved

[wizilling]

Hi,
i have this problem where my asp.net pages dont get started if i run them from the visual studio.net application.
(i am using the graphical programming methond and not through notepad)

i put in a command button and then when i play the play button to build and run the project, my webform wont start.
My IE doesnt get launched at all when i run it from applicatoin. the error i get is "Error while trying to run the project". However if I check the output for the build, it says that Build Succeed, 0 errors 0 failed.

i have also tried running "aspnet_regiis.exe -i" command but that doesnt fix this error.

however when i type in the url Http://localhost/webapp1/webform1.aspx then the project is show successfully on the browser. only my vb.net application wont start my asp.net pages.

Sounds like your ISAPI mapping is screwed up. Open command prompt run aspnet_regiis.exe /i. This will reinstall current version of ASP.NET.

This file is located in WinDirectory\Microsoft.NET\Framework\YourVersion

i already re-installed that. but the problem still exsists.
