I have a Windows 7 Ultimate 64-bit computer with 8 GB RAM, Quad Core AMD Phenom 3 3.4GHz and I received "Unable to activate DirectSound for selected device. DirectSoundCaptureCreate failed. HR=DSERR_NODRIVER. No sound driver is available for use" message. This software worked on a Windows Vista Home Premium laptop and a Windows XP computer. What can I do?
