Microsoft Office Project Professional 2007 is required for this action

There is a common error that we see at a lot of client sites and on machines of our own. The solution happens to be fairly easy. First the symptoms of this issue.

Symptoms:

You go to the Resource Center in Project Web Access. You select a few resources that you wish to edit and click the open button. You get the following message:

“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”

Fix:

1. Launch MS Project Professional 2007

2. Help menu -> Microsoft Office Diagnostics

3. Click the Run Diagnostics button.

MS Office will run check and perform corrective actions.

4. File -> Exit to exit the Project Pro

Reason:

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-registers the Project Pro 2007 application and sets as the default application as MS Project Pro 2007 to open MPP files.
