The "answer" given by halovapor on 2/6/14 is not an answer. Someone at Digi needs to address this. I have had this same problem in both Windows 7 and 8 and there is still no clear support thread for it.
halovapor suggested installing the updated drivers. That is not the problem. It is the Edgeport Configuration Utility. Also, if you download the Readme files that go with the drivers, it lists the configuration utility in the contents of the install package, but it is not there.
Someone at Digi needs to fix this. Either put the updated (Win7/
configuration utility in with the driver install like it says in the readme, or set it up for download separately in the support page for Edgeports. Currently there is no Windows 7 or 8 OS option in the download section for the Edgeport Configuration Utility.
