They have compatibility issues with Windows 8, and whilst they will install, testing has found that they are prone to crashing constantly on Windows 8.
Windows 10 is based on the same engine as Windows 8, so whilst we have not performed actual testing of PlansXpress v1, v2 or v3 on Windows 10 we think it is a safe assumption that the same will apply.
