Windows 10 Controlled folder access
In the latest fall windows 10 version 1709 update. There is a new setting called controlled folder access. It is not turned on by default at the moment. It maybe turned on by default in windows updates later on or the user may have turned it on.
When opening Image Editor, planner, or proposal. You may get a warning from virus & threat protection that it has been blocked.
If you click on the warning. It will take you to a settings page. Click on the plus sign to add an alllowed app and navigate to the following folder location C:\Program Files (x86)\Drafix\PRO Landscape on your computer. You will need to click on the ImageEditor.exe, Planner.exe and Proposal.exe. You can't add them at the same time. You need to add them one at a time.
You should have 3 entries after adding them to the list. Try opening the program to see if it fixed the issue.
