General compatibility
The Davis Weatherlink software is compatible with all recent versions of Windows from XP up to and including Windows 8.1 and there are no known compatibility issues at all.
Windows 10 is also fully compatible, but users can occasionally encounter issues in getting Weatherlink to run correctly with a new or recently updated copy of Windows 10. These issues can usually be fixed and are detailed under the separate Windows 10 topic.
Users of serial (RS232) and IP loggers, including those on Windows 10, are also largely immune from compatibility issues but those using the USB logger version need to take a little more care.
USB drivers and apparent compatibility issues
While there are no fundamental compatibility issues with the Weatherlink software itself, there is one type of communications problem with the USB version of the logger that can be caused by an incompatible USB driver – this happens if a new version of Windows is no longer fully compatible with an existing USB driver or if a faulty driver has inadvertently been included with an automated Windows update. This issue may appear after Windows has performed one of its regular automatic updates or if transferring Weatherlink to a new PC with the latest version of Windows. (To understand the difference between the main WL software and USB drivers please refer to the Understanding WL Comms & Issues topic.)
This issue of USB driver incompatibility has recently resurfaced with automatic updates to Windows 10 (see below) but can also be seen if a user attempts to use an old version of Weatherlink on a modern version of Windows. If you suspect this issue on a Windows version prior to Windows 10 then be sure to update Weatherlink to the latest available version (as described in the Migration topic) before concluding that it is indeed a new compatibility issue – the latest WL version will also install the latest available and validated version of the USB driver.
