Will TRAC4 work on Windows 8, 8.1 or 10?
Yes, but as with Windows 7, the user must have certain Administrative rights for full functionality.

After installation, TRAC4 doesn't recognize the DL-1 is connected. I rebooted and still not recognized. What now?
The USB drivers may not be installed on your system. This sometimes happens with Windows XP. The USB drivers can be downloaded from the Software Download page.

Does the new software work with the older DL-1?
No, the new TRAC4 software works only with the latest version of the DL-1 hardware.

How do I tell if I have the new DL-1 or the older DL-1?
The easiest way to determine if you have the newest (2011) version of the DL-1 or an older version is to determine the shape of the DL-1 case. The older versions have one flat side and then a rounded side. the latest versions (2011) have four flat sides. there is a picture of both on the Software Download page.

Does the TRAC4 software run on Windows 7 and Vista?
Yes. However, the TRAC4 program requires some Administrative rights on Windows 7.
