Help I'm newbie

I just try to install a USB converter to Serial RS 232 adapter on my Vista Home Premium desktop but it won't load the driver software. The error code 31 appears in device manager. Can somebody help me?

Try this
Cannot Access CD-ROM and "Code 31" Error Message in Device Manager After You Remove Adaptec Easy CD Creator from Your Computer

Good luck

Thanks for trying to help me. I followed your instructions, but then there are no Upperrfilters or Lowerfilters named files on this location. Haven't tried the second method cause yet.
