Error showed when start Axapta 4.0 client referent to the ActiveX Control CmxPhone.

When axapta client is started, and an error messaje is showed like the following:

Unable to create ActiveX Control.
CmxPhone Control

With that message, axapta can run but always the message is showed. To correct the problem, is neccesary do the following steps:

• Go to Start->Run and type cmd to load the command window.
• run the following command: regsvr32 c:\Program Files\Microsoft Dynamics Ax\40\Client\Bin\smmPhone.ocx (Suppose that the client is installed on the path c:\Program Files\Microsoft Dynamics Ax\40\Client, else, use the path where the Ax Client is installed and use the Bin Folder)
  

If the control is registered without any problem, the message won't be showed again.
