Report Viewer wont run

[Tango]

Hi,
I have dragged the report viewer control onto my aspx page & completed the
report viewer task (to remote RS2005 server) Report & page works fine when i
view in browser from vs2005. Problem is page wont load on any other machine.
error message is Required attribute 'appliesTo' not found.

line 29 of the code is highlighted which is the following

Line 29: <add extension=".rdlc"
type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.Common,
Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>

thanks in advance
