File loading warning - security concern (executable file).

When trying to load a LSP or VLX file with an add-on application, AutoCAD displays the warning dialog "An executable file was found outside of the specified trusted locations. What do you want to do?". How to get rid of this warning?

This is the default setting in AutoCAD 2014 - it warns before loading of any add-ons located in other than "trusted" directories (trusted folders).

You can disable this security protection with the variable SECURELOAD (to 0) but the right and safe way of suppressing the waring dialogs is adding the folders with your add-on applications to the list of trusted locations (folder paths). You can do this using the variable TRUSTEDPATHS or more conveniently using Options > Files > Trusted Locations.

If you have your application directory split into several subfolders, you can add them in one go using the special three-dots notation. E.g. the folders:

S:\Applications\My
S:\Applications\CADstudio
S:\Applications\Melange

can be added to trusted folders with a single:

S:/Applications/...

The AutoCAD program folder and all folders used for the applications from Exchange Apps are automatically considered as trusted/secure.

Besides SECURELOAD you can also disable this mechanism using the Options dialog. On the System tab, click "Executable File Settings". All files ARX, DBX, HDI, LSP, FAS, VLX, MNL, DVB, DLL, SCR and other are considered as "executable". Here you can set whether the external functions will be loaded only from the trusted locations, or from anywhere and whether the warning dialog will be displayed. The bottom part of the option dialog is driven by the variable ACADLSPASDOC.
