about unpacking dialog

My installer is 44 MB.
I used lzma solid compression .
but unpacking dialog cant't show.

I want the installer to show this dialog.
Because unpack data need some time,
the user can't see the window or tip in these time.

how can i do this?? thanks!

look at this:

That dialog is only displayed if data is unpacked in .onInit.

I know that you are Chinese, the same as me.

Do you use the command "CRCCheck"?

I have found a problem!

I use the following command:

function .oninit

Banner::show /NOUNLOAD /set 76 "setup is unpacking" "wait...."

Banner::destroy
functionend

I can see this unpack diglog!

why?

use ReserveFile command

Reserves Banner.dll
