Problem: A dialog box titled “File Loading – Security Concern” that says “An executable was found outside of the specified trusted locations” is displayed when Design Master files are loaded in AutoCAD 2014 or later.
Solution: If you are loading Design Master for the first time, press the “Load” button and ignore the dialog boxes. Once the installation is complete, AutoCAD will be configured to no longer display these dialog boxes.
If these dialog boxes appear when AutoCAD is opened or a drawing is opened, run the DM->Help->Installation Settings command. Leave all of the settings alone and press OK. The command will configured AutoCAD to no longer display these dialog boxes.
Design Master configured the TRUSTEDPATHS system variable to include the install folder to eliminate these messages.
1. Run the OPTIONS command. Go to the Files tab. Add the folder where the file is located to the Trusted Locations path.
2. Set the SECURELOAD system variable to 0. Using this value will load all files without any warning messages. This solution is not recommended.
