This operation requires that Microsoft Project Professional 2010 & project Server 2010 RRS feed

  • Question

  • Issue description :
    Myself and My Project Manager are unable to open/create an enterprise calendar from within PWA 2010 in Project Professional 2007 (we're running in backwards compatibility mode).  When they try, the below error message is received.

    I have confirmed that they have their accounts set-up correctly for Project Pro 2007, and the URL matches exactly under Tools, Enterprise Options.   I have tried this on XP with IE8 and Windows 7 with IE9, anyone and everyone gets this error only when you try to create a calendar.  I have confirmed that protected mode is off on IE 9. I have checked all settings and this is the only problem we have ran into.

    Error Message:

    "This operation requires that Microsoft Project Professional 2010 or Microsoft Project Professional 2007 to be installed and configured to connect to a profile for this Project Web App site. If Project Professional is loaded, ensure that it is connected to the profile for this Project Web App site and that there are no dialog boxes open."


    I have tried just about everything I can think of - reinstalling Project Pro, reinstalling IE 8 and 9, patching Project Pro and Office etc. Reviewing other topics on the issue didn't resolve it for me. I patched Project Server 2010 in BCM, and re-installed it, nothing get past this one issue. All other aspects of Project Server 2010 work fine.

    Any ideas would be appreciated....

  • LeLand,

    You'll probably get a better answer if you post to the Project Server forum at, This forum is dedicated to questions/issues with the stand alone installations of Project.

  • Hi Leland,

    Quick check, are you able to open Project Plan via PWA with option edit in Project Professional or are you able to open Enterprise Global launch via PWA site?

    Also URL of the PWA site entered in IE address bar as well as Project Professional user account profile should be identical.

    Add PWA site URL as trusted site in IE and set security level of trusted sites zone to low.

    Try opening IE using "Run as Administrator" option

  • Hi there,

    You'll need the Project Server 2007 PWA activex control to do this and other functionality such as open projects from PWA 2010 in Project Professional 2007. See:

    It will be good to test on a test client machine.         

    Hope that helps.
