How to speed up the process of initial dialog (Installscript project)?

[cruisehung]

I'm using Installshield 2015 professional edition and created one install package.
But the initial dialog takes long time to prepare before welcome dialog.
Is there any way to speed up the initial process?

Thanks!

Try setting your "Minimize Initialization Time" setting in Setup.exe tab of your Media->Release selection in IS.

Hi, thanks for your reply. But that feature is not for reducing the initial process.
It's just for having minimum time to display custom logo.

Under Media > Releases > Build tab
try Compression = uncompressed
or
try a different Cab Optimization Type MSZIP | LZX

Thank you for your suggestion.
In InstallShield2015, there's no compression feature in build tab. But I found it in "Organization" --> "Component".
There's no difference after set "compressed" to "No". It still took long time (about 5 sec) for initialization.

I'm expecting some tricks to remove unused item/dialog to shrink the file size.
