Carlson 2016 running on IntelliCAD® 8.1 is the only version that officially supports Windows 10.
At this time, Carlson Software does not recommend upgrading to Windows 10 with any other version of our software until
we’ve had the opportunity to thoroughly test software compatibility with the new operating system.
We should have more information once we have been able to analyze the spectrum of issues. Until then, we advise users of
existing versions (excluding Carlson 2016 with IntelliCAD® 8.1) to abstain from installing Windows 10 upgrade to avoid
downtime.
