Install dialog ?

[Sharpie]

How can I bring up the Windows Installer dialog to search for the software package to install ?? (this dialog is one you often see when you try to install a package that is not available on your system and it asks you to insert your CD or locate the executable file)
When this dialog shows up, I look at my Task Manager and find that it is embedded inside explorer.exe, I am amazed at how that is done indeed.
Is there an API to call it anyway ?

Thanks.

I've never seen this pop-up to install software. Only device drivers, if the device is unknown to Windows.

Well, it's not that windows I guess.
Thank you.

Well, it's not that windows I guess.

So maybe you provide a screenshot to let us do no guessing?

Thank you,
I would like to know the dialog signature in the following image. I would like to call it with some known API function if available.

There's no API on this. The dialog belongs to Windows Installer, and is controlled by WI inner logic.
