Installshield Custom Dialogue Installer

I have built an Installshield installer successfully..and it is up and running..But I am a few customization away from perfection .While asking for administrative privilages in the course of installation..The permission seeking Dialog box shows weird message.which is unpleasant to anyone .I am attaching the screenshot below..

As I am new to Installshield Premier edition..can anyone please help me out with this- how can I change the pointed string AND ALSO the publisher name from unknown to my name(if possible)?

UAC Prompt: "If you Authenticode-sign your .msi package, Windows will show that as the name. Otherwise, you get MSI's temporary copy of it, which has a random name." (from Bob Arnson's answer here (WiX developer & overall master of conciseness).

So you need to get a digital code-signing certificate - if you don't have one - and then you will get rid of this problem once you sign the MSI package.

Technically you use the /d command line argument when executing signtool.exe to sign your MSI file (source - Scott Langham). I believe you specify the name you want displayed with this option. Also see this answer.

Code Signing Certificate & SmartScreen: Please see this answer for more details on signing, Installshield and the issue of trust and SmartScreen / Windows Defender (very important issue): How to add publisher in Installshield 2018.
