You can have a WAV file and not have a Microsoft WAV file, the most common version.
Also given Windows, you may not have a WAV file at all.
You can force Windows to show you what you really have by revealing filename extensions.
– Hidden File Extensions
– Start > My Computer > Tools > Folder Options > View > [ ] Hide Extensions for Known File Types (deselect)
– Apply (to this folder) or Apply to All Folders
– OK
If you have a foreign file, you can add the FFMpeg software to Audacity and open the file that way.

How did you turn the Reaper project into a WAV file?
Thanks guys! I tried the software that you recomended and still it doesnt let me open wav file from Reaper. The way that I am doing it is by duble click on the track in Reaper. I put Audacity as the prime extarnal Editors in Reaper. Supposedly should not be a problem with it, I sow tutorial on youtube that what exactly what he had done. I tried also to export the project to my desktop, and then open Audacity and open the file from the Audacity but he gave me the same message 
Export the file from Reaper as a WAV file, then in Audacity use “File > Import > Audio”.
