INNO Setup [CODE] block, set status?

I have an installer that needs to install some visual c++ redistributables before anything else gets installed. This is because an ActiveX COM object wont register without it being installed first.

I have the code that properly installs the visual c++, but the program seems to hang for a minute (to the user) while it is installing since they have no clue what is happening. Is 开发者_运维问答there any way to inform the user what i am doing without popping up an actual messagebox? Like how you can set the status in the [Run] block.

// This function will be called after the last "Next" button is pressed, but before any files get installed
procedure DoPreInstall();
var
    ErrorCode: Integer;
begin
    Exec(ExpandConstant('vcredist_x86_2008.exe'), '/q', '', SW_SHOW, ewWaitUntilTerminated, ErrorCode)
  end;
end;

I haven't tried it but I found this: http://news.jrsoftware.org/news/innosetup.code/msg21747.html.

It might help. Another is to run the vcredist in a non-silent mode.
