Customizing dialogs on update

[Fallen_Zen]

Hello,

I'm new to InstallShield and wanted to ask a simple question. My app is currently one exe file.
I would like to show only the progress and success dialogs on installing an update. This can be full reinstall, it will be short with one 200KB file. Is it possible?

Here are the steps I want to provide:

Installation:
1. Welcome Screen + EULA
2. Destination Path
3. Progress
4. Setup Complete

Update:
1. Progress
2. Setup Success

Thanks in advance!
Peter

Is it possible or not?
