Using SharePoint 2010 foundation on a newly installed Windows Server 2008 R2 x64 box. The default SharePoint site works fine. After I installed SharePoint Designer 2010 x64 I go to the site and select "Edit this page in SharePoint Designer" every time I get the popup screen that says "This feature requires SharePoint Designer 2010, Please Download"
I have verified that I am installing 64 bit Designer, on 64bit SharePoint
I have reinstalled SharePoint Designer.
I have "repaired" the SharePoint Designer install and still I get the download message.
I can open SharePoint Designer and open the site manually but the site does not recognize that SharePoint Designer is installed.
I have also opened centeral admin and enabled all of the SharePoint Designer check boxs for the site.
