When attempting to use the Import/Export .wav File function or Multitone Creation Utility, an error message similar to Figure 1 below may be displayed. This indicates that an OCX file (Microsoft Object Linking and Embedding Control Extension) is not registered correctly.

To fix this problem requires that the DspRiff4.ocx and/or Makewave4.ocx controls get re-registered. The Makewave Utility utilizes both the Makewave4.ocx and the DspRiff4.ocx controls, while the Import/Export function utilizes only the latter. Proceed as follows:
1) Select Run from the Windows Start menu.
2) Enter the following command in the box and click OK.
regsvr32 "C:\Program Files\Common Files\Audio Precision\DspRiff4.ocx"
Note that the program files path may be different in international versions of Windows.
3) If registration of the control was successful, a message similar Figure 2 will be displayed.

4) Repeat the process for the Makewave4.ocx control if necessary, using the following command:
regsvr32 "C:\Program Files\Common Files\Audio Precision\Makewave4.ocx"
