Hello anniewhite -
It is normal when installing from CD that the installation asks to check for an updated version of the software. The CD is not needed - it is included so that the device could be installed even if there is not an internet connection available. Each 3dxsoftware download from the web site contains the complete software - the driver plus the add-ins.
To find whether the problem you are seeing is the device not being recognized or not working in an application you can use the trainer or the Jet Demo.
The circumstance where the order of installation is important is for applications that use a 3Dconnexion add-in like SolidWorks, SolidEdge, Maya, 3DsMax, Photoshop and SketchUp. The application must be available for the add-in to be installed.
If the application is installed later the 3Dconnexion installer needs to be run again using the Repair mode. The installer asks whether you want to uninstall or repair the software. Repair mode can be used from Add|Remove Programs [Win7 Programs and Features]
Which device and OS are you using ?
Is this a new installation ?
Have you tried other USB ports on the PC or tried it on a different PC?
