Problem when installing MS SQL Reporting Service

Hi,
I need help.
I am trying to install the Reporting Service.
When the screen was in "System Prerequisites Check", it tell me that
visual Studio.NET 2003 is not installed.
After clicking next in "System Prerequisites Check"
It jump to a page called "Welcome to ...SQL Reporting Service SETUP"
and then it automatically jump to a page called "Installing Reporting
Services"
But I haven't selected anything.
Then wait a few minutes, a general error message appears and and tell
me "... was failed to install Reporting Service" with the "Send Report"
and "Don't send" button.
Could anyone get the solution? Thank you very much.I am facing similar problem while installing Reporting Services.
At the "System Prerequisites Check" all checks are OK but at the
"Welcome to Ms SQL Server 2000 Reporting Services Setup" screen I
waited for 10-15 minutes for the NEXT button that never appeared.
Finally, a general error message appears and telling
me "... was failed to install Reporting Service" with the "Send Report"
and "Don't send" button.
Can someone help?|||I have resolved the problem by doing a windows update, shut down all
the active applications. Then proceed with the installation.
Your installer may be corrupted if this doesn't help.
