Trying to install Reader 9.0, XP Pro. Installation of Reader gets to 99.9%, then "Crystal SoundFusion Setup" install program fires up. I haven't the slightest what Crystal SoundFusion is, but I click "Next" to let it install, then my CPU goes to 90% (and will stay there for hours if I let it) and I get an indefinite "Please wait..." message from the installer. Only way to stop it is to kill the CRYSETUP.EXE process. After that, Reader 9.0 is not installed.
