The Windows 10 Fall Creators Update breaks all programming languages that create and write to file systems. This includes the language that Aeromed Software uses. Basically, if we try to delete a local file, and then make the assumption that the file is actually gone, the subsequent programming will fail with a program error. This error was introduced in the Windows API/file-system level and thus affects all programming languages.
We recommend that you do NOT update to the Windows 10 Fall Creators update at this time. You can tell which version you have by looking under system properties - the Fall Creators Update is Version 1709.
We are waiting for word fro the developer of our programming language to see if they can establish a fix or to see what Microsoft does about this error.
