For protecting files created with Lectora (www.trivantis.com) the following steps are necessary.
Step 1 - Select Publish in Lectora
Within Lectora, select Publish. As publish option, select Publish to Single File Executable.

Step 2 - Import files in Multimedia Protector
Now import all the files from the project folder and mark the EXE file as start file using the button Define as starting file. A red icon signals the start file.
This supports all options of Lectora but with the limitation of the EXE protection.
