Program license key

I have a DAM program that periodically has updates into which a license key is inserted to verify that I have purchased the program. Years ago, actually. Somehow I must have pushed the wrong button on the Avast pop-up warning me the key was a *.exe Avast could not verify, and the license key won’t run and insert into the DAM update. How and where do I reverse the block for this key, and label it to always be allowed.

Thanks much,
BAB

The problem resolved itself after restarting. ??Who knows?? :)Thanks.
