I have checked the file type and all the information indicates that this isn't an audio file. I have also tried to download the application, but the official website is not working properly. Secondly, if you have it installed on your computer, export the file to another format, because there is no compatible application to convert VC2 file to WAV.
Secondly, if this file format is proprietary, then only the application which creates it has the capability of exporting to another format.
