When I open a project created with Studio 2015 in a standalone application with 'new FileBasedProject', a LicensingException gets thrown with the message: A valid SDL Trados Studio Professional license is required to use the Project Automation API in a standalone application.

Some observations:

1) I have SDL Trados Studio 2015 Professional with a valid license.

2) The standalone application exe file and the DLLs on which it depends are installed in the Studio4 folder of the SDL installation and I run the exe file from there.

3) SDL Trados Studio is closed when I run the application.

4) This problem is similar but not identical to other license problems in standalone applications that I have found in the forums.

Thanks in advance for any help.
