As PATGuard 2 is an obsolete product it will not be tested on Windows 10. PATGuard 3 will be tested on Windows 10 once it is released.
I would advise you to update to PATGuard 3 as it is backwards compatible with all Seaward testers (there is a full list on our website) and has additional functionality. Please see the PATGuard 3 pages on our website for full details on how to upgrade.
Thanks and kind regards
