64 Bit - New Dell computer-audacity wont work

Dear Group. I downlaoded the latest version of Audacity. I keep getting an error message
that the program cant open the sound device. The Dell computer is brand new 64 bit machine.
Not sure what to do.

See this FAQ in the manual: http://manual.audacityteam.org/help/manual/man/faq_errors.html#sound_device
