Hello Jassim,
If you are referring to the UAC prompt (for user account and password) during installation, please keep in mind this is the normal behavior when using an installation type which requires admin privileges. To avoid this behavior you can choose to use a "Per-user only" installation type from
"Install Parameters" page.
Let us know if this helped, otherwise please give us more details about your installation scenario requirements. Maybe exemplify a bit more or attach some screenshots.
All the best,
Daniel
