problem in registering comdlg

I have a problem while using Microsoft Common Dialog control in Navision financials 2.01A version.When I declare the Common Dialog the following error message appears: The OLE control or Automation server identified by ‘Microsoft Common Dialog Control 6.0’.common dialog requires design time Licence.This licence cannot be obtained.Make sure that the OLE control is installed correctly with appropriate licence. I had also used regsvr32, and got the message- Dll registerserver in c:\winnt…was succesfully registered. But still face the same problem while using that ocx in navision. If anybody have the solution…please let me know. Thanx in advance
