Business Portal MBFWebBehavior recurring Error Message

When end-users accessing Business Portal from their client workstations, an error message pops up on the screen requesting to download the required “.dll files” in order for MBFWebBehaviors Product to work correctly.

• Program Name: MBFWebBehavior.cab
• Verified Publisher:  Microsoft Corporation
• File Origin: Downloaded from Internet

MBFWebBehavior.cab Error Message

Technically speaking, two dll files are missing since the user doesn't have “Administrator” privileges to access the folders in which those dll files are to be downloaded.

The result is, the message keeps popping up on the end-user screen forever, these dll files are shown below;

• MbfWebBehaviors.dll
• Msvcr71.dll

There is a support article from Microsoft explaining thoroughly on how to resolve the issue, No.905429. 

To me, I found it more easily to log off from the windows and sign in with the “SPAdmin” account, then access the business portal in order for the error message to pop up again. Click (Yes) in order for the dll files to be downloaded correctly, and the end-user can get back to accessing Business Portal without the headache of the recurring “MBFWebBehavior” error message.

Important Note ! 
When opening the internet explorer, right click on the program and (run as administrator).
