Hello David,
First of all, I apologize for the inconvenience!
Regarding the issue, just a quick not would be the name of the setup being "setup.exe". As far as I know, it's not really ok to have such name for your setup as it increases the chances of it being detected.
Now, what I would suggest is the following:
- whitelist locally the folder where the setup is built / whitelist the EXE
- submit the EXE for whitelisting on Microsoft website:
Submit a file for Malware Analysis
I know this can be annoying in some instances, but I'm afraid there isn't really a workaroud to this - as we do the same + scanning each file individually.
Thank you for your understanding!
Best regards,
Catalin
