The computer on which you are creating the Data Analysis view must be able
to download the required ActiveX controls that contain the Office Web
Components, or the components should already be installed. To facilitate
installation of the controls, you should temporarily do the following in
Internet Explorer:
- Add the Project Web Access site as a trusted site.
- Clear the option to Block Pop Ups.
- Enable Access data source across domains. You can change this setting
through Internet Options by configuring the Trusted Sites Zone security
settings.
