USB autostart program

Paul

I realize this topic has been discussed before but I hope what I am asking is
just a bit different. I have a program on a USB Flash Drive (it is a
password manager). The program is supposed to start automatically. Whenever
I put the drive in a USB port a window pops up that askes me what I want to
do, I can click on the program or No Action. I click on the program and the
window goes away and everything is fine. There are no choices available to
"always do this" nor am I able to pick that option via the drive properties.
I don't want that window to pop up but I do want the program to
autorun......how can I do this? Will using Tweak UI to prevent the drive
from autorun also prevent the program from autorunning? I just want to
eliminate the window, not prevent the program from running. As of now the
program will not autorun as long as the window is there. Thanks for any help
I can get. Paul
