Import – Export .wav File and Multitone Creation Utility Error: “The Reference Could Not Be Added”

Created on 2009-11-02 23:28:00

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.

Figure 1. OCX file.

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 FilesCommon FilesAudio PrecisionDspRiff4.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.







Figure 2. Registration successful.

4) Repeat the process for the Makewave4.ocx control if necessary, using the following command:

regsvr32 “C:Program FilesCommon FilesAudio PrecisionMakewave4.ocx”
