Problem adding an Exclusion

I have installed a trial version of an Astrology Program, which allows enrolment of a chosen Word Processor, such as MS Word or Libre Writer, etc.

This call on the Word Processor is not functioning unless I turn off Bitdefender AV Free Edition.

Adding an exclusion of the whole folder of the Astrology Program, or the .exe files within it, has no result.

Nor is there any mention in the event log of a program being blocked.

Any help would be appreciated!

Cheers
