When you deploy Configuration Manager 2007 on servers with an x64 Operating System like Windows Server 2003, you can face some problems in conjuction with the Office Web Components.

Office Web Components are required to display charts and graphs in your reports. Even if you install the Office Web Components, charts and graphs in reports running from an x64 Reporting Point are displayed.

The reason for this is that the Office Web Components are 32-bit and so do not function on a x64 Reporting Point with IIS running in 64-bit mode.

Symptoms are errors like:
This report has a chart, but the Microsoft Office Web Components required to view charts are not installed on the Reporting Point. Please contact your administrator.

To solve this issue you need to configure IIS to run in 32-bit mode. To change the IIS mode to 32-bit, run the following command:

Cscript adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 true

Keep in mind that no other 64-bit applications reside in IIS, because they will fail in 32-bit mode.

Good luck!
