SQL ReportServer 2005 on Win Server 2008 & IIS7 gets "unable to load client print control"

I have SQL Reporting Services 2005 running on a Win 2008 server with IIS7. SQL and RS have all of the latest patches applied (as of 11/19/2009). When I access a report through Report Manager on the same server or ReportViewer on a different IIS server I can not print. I get the "unable to load client print control".

This occurs with 开发者_运维问答IE6, 7 and 8. All clients are running with administrative rights. I do get prompted to download the component which seems to occur but then I get the above message.

This same configuration works fine in a test environment, the only difference is the SQL and IIS servers are running Win 2003. TIA

The issue has been resolved through applying the latest service packs and any hotfix rollups that were available on 11/21/2009 (SQL server 2005 running on Win 2008)
