Opening the Enterprise Resource Pool from Ms Pro

Really good forum answer that addresses a “mystical” problem I had been facing.

Thanks to Chak from www.epmcentral.com.

Error
“Microsoft Office Project Professional 2007 is required for this action. ensure that your copy of Project Professional 2007 can connect to this server. If both of these conditions are true and you still get this message, contact your system administrator for assistance”

Solution
FYI, reason beyond the error: MPP file extensions are setup to open with default application MS Project. You have both the versions of MS Project Pro installed on your machine. In your case, your MPP file was setup to open with default application MS Project Pro 2003. (You can verify it by opening the any MPP file from your local machine. You will see the MS Project Pro 2003 will launch by default. But now you may see 2007 as you already fixed the issue.) When you are trying to open resource info from PWA, your machine is trying to invoke MS Project 2003. So, you are seeing the error “”Microsoft Office Project Professional 2007 is required for this action. ensure that your copy of Project Professional 2007 can connect to this server” When you ran the Diagnostics, it re-register the Project Pro 2007 application and sets as the default application as MS Project Pro 2007 to open MPP files. So, now you able to open the MS project 2007 by invoking it from PWA.
