Pass argument (/verysilent) to application (subinstaller) executed from Pascal code in Inno Setup

I am trying to run the exe in silent mode, but I don't know how I can do it with the command line option. Below I have attached my script.

var progress:TOutputProgressWizardPage;

procedure DownloadFinished(downloadPage:TWizardPage);
var ErrorCode:integer;
begin
 if ShellExec('open', NewInstallerPath, '',
   ExtractFilePath(NewInstallerPath), SW_SHOW, ewNoWait, ErrorCode) then
   ExitProcess(1);
end;
Solution

  • Arguments (like the /verysilent) go to the third parameter of the ShellExec function:

    if ShellExec('open', NewInstallerPath, '/verysilent',
     ExtractFilePath(NewInstallerPath), SW_SHOW, ewNoWait, ErrorCode) then
