Error message: No Sound Card installed - Was bad .wav files

My guess is that the fact you have Windows installed on the D drive might be part of the reason?

By default, when you install any software of drivers it will go in the C drive and perhaps you have drivers or software installed in the wrong directory which would explain this problem?

I would still recommend a fresh new installation on the C drice in NTFS this time but again, it's just a suggestion and it's what I would do because your setup is still not normal.

Regards
