connecting psr-800 to new computer

Hi everyone, longtime posting here had no problems UNTIL I setup my new DELL 8700 computer with windows 7 professional operating system. Using my old computer which had windows XP I changed the com port under the device manager to com 6 and everything worked great. under Windows 7 I went to device manager and didn't notice a designation for that. Anyone running Windows 7 , I would appreciate any help you can give me with setting up the Grecom 800 so I can update my scanner ??????
