Nevermind. This post from Craig Borowski resolved the issue:
"Before we proceed with trying to change COM numbers, let's try running the program in Compatibility Mode. Right click on the program and select Properties. From there select the Compatibility tab and choose to run the program under one of the Vista modes. If that doesn't fix it then proceed below to change COM settings.
First open up the Control Panel and from there select the System and Security category. Towards the bottom of the list that appears you should see Device Manager. Click on Device Manager and a new window will open up. Look down the list for the Ports (COM&LPT) option and click the + sign to expand the list. If there is a Generic Device listed, right click on that and select Properties. (If there is not a Generic Device listed, then expand the Universal Serial Bus further down the list and see if you can find it there. If you do, right click and select Properties.)
Now choose the Port Settings tab and from there click Advanced. At the top of the new window you will be able to select a new Com Port Number. Assign it either 1, 2 or 3. Then click OK to exit that window. (Windows 7 should automatically register the change, but you may need to hit Refresh Devices or Scan for New Hardware from the Action menu above.)
Then try running the program again. If it still does not find the device, try restarting the computer and trying again.
Finally, if we still aren't having any luck, try updating the 7096 firmware. First uninstall the existing version of the 7096 software and then go to this page and download the software. When you run the program, you need to have the 7096 connected. This will update the firmware on the 7096. Please be patient and wait for this process to finish... otherwise the unit can be damaged. After this has completed, try running the newly installed software."
