Step 1: Use Microsoft Register Server (regsvr) to Manually Register Your WDec3.ocx File
When you install Intelliscore Polyphonic WAV to MIDI Converter, or another software that uses the WDec3.ocx dependency, the software should register the file automatically. Sometimes your OCX file won't get registered properly and will trigger a "WDec3.ocx not registered" error.

- While holding CTRL-Shift, hit ENTER.
- You will be prompted with a permission dialog box.
- Click Yes.
- Type this command: regsvr32 /u WDec3.ocx
- Hit ENTER. This process will UN-register your file, allowing you to RE-register it.
- Type this command: regsvr32 /i WDec3.ocx
- Hit ENTER. This process will RE-register your file.
- Close the command prompt window.
- Re-start Intelliscore Polyphonic WAV to MIDI Converter.
Step 2: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.
