Hi VistaOwner,
Prior to your post, I hadn't noticed that SoundSoap was not installed on either x86 or x64 versions of Vista Ultimate. I just assumed that the functionality of SoundSoap was integrated into the Sound Editor. However, I just checked my XP x64 installation and SoundSoap is installed separately (in its own program menu group - "BIAS").
Apparently, as Beerman stated, even though EMC9 is [questionably] Vista Compatible, SoundSoap is not, and therefore not installed. I just checked the
BIAS-INC system requirements for SoundSoap, and there is no mention of Vista compatibility.
