Windows Open File – Security Warning


Since I updated the cad.exe file, Windows is showing a ‘Security Warning’ when opening RealCAD / LANDWorksCAD.

How can I avoid Windows asking me every time?


Once Windows shows the security warning, make sure to uncheck the ‘Always ask before opening this file’ option.

Next time it will open RealCAD / LANDWorksCAD / ArborCAD straight away.
