i'm sorry amount of code present , don't expect perfect answer if understand did wrong, pleased. also, when add the file ignored antivirus, doesn't launch.

note other qt programs work fine i'm convinced due code.

i had same problem avast. wasn't qt specific thing. avast blocked programmed.

you have go settings , uncheck box says "unknown source". avast doesn't know program comes , blocks because may virus. @ least that's avast did programs. after unchecked checkbox worked fine.
