False Positive in Governor of Poker 2 Premium Edition?

(Hope I'm posting this in the right place.)

Anyhow, I bought and downloaded "Governor of Poker 2 Premium Edition" -- Norton's even said that the file was fine.  However, upon installing the game, Norton's responded with a warning of "Trojan.Gen.8!cloud."  Not sure how a file could be fine and then not fine, but there it is.  My clipboard came back with the following.  Clearly some users have "allowed" the file, but I'd rather some confirmation first before overstepping Norton's "judgement."  (I already tried submitting this to https://submit.symantec.com/false_positive/ , but wasn't able to for various reasons.  File size, etc.)  I'm running Norton Security with Backup 22.9.1.12 on Windows 10.
