Error Message when using context menu

Just bought and installed NOD32.

When using the context menu in Explorer to scan manually or even using the NOD32 module, I get the following error message:

"Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Office Outlook and set it as the default mail client."

Huh? I have Office installed, and hence Outlook, but I have Outlook Express as my default email client.

How do I stop this annoying behavior?

 

If I remeber correctly.....Open NOD's control center then select "nod32". click "run nod32"..Go to the "setup" tab and uncheck "use MAPI interface" for the"context menu Profile" or all your profiles.... With "use MAPI interface" enabled you will get that message if Outlook is not your default client.
