Progress bar for CRCCheck?

Not much to say,
As the title speaks for itself.

Still, is it possible to have a progress bar for crccheck?
What should happen is that when execution starts,
A small window will popup with a progress bar that
will show the progress of crccheck operation.

I am new to NSIS scripting.
To tell the truth I don't need it for creating any setup,
Not now anyway.
Playing with it just like any other programming/scripting tool.
I used to be afraid of its' syntax and still a little afraid.
(Not new to NSIS itself cause I know about it for at least three years)

You would have to build a custom version of NSIS by modifying the source code and recompiling the stubs, not an easy task if you don't know the C programming language.

I know very basic C programming which is inadequate
For this work.
Thank you for replying. 🙂
