ShellExec

[Terry Rizzo]

Hello,

I am trying to launch a security key setup exe using a command window.

Using the following code generates an error: “The system cannot find the path specified”

  CommandStr := ExpandConstant('"{cmd}"');

  ParamStr := ExpandConstant(' /k ""{app}\System Driver\Sentinel System Driver Installer 7.6.1.exe"" /v ""/passive CONFIRMUPGRADE=TRUE REBOOT=ReallySuppress ADDLOCAL=ALL"");

  ShellExec( 'open', CommandStr, ParamStr, '""""', SW_SHOWNORMAL, ewWaitUntilTerminated, ResultCode);

If I just open a command window manually (as admin) and enter the following, it works as desired:

"C:\Program Files (x86)\Company\Application\System Driver\System Driver\Sentinel System Driver Installer 7.6.1.exe" /v "/passive CONFIRMUPGRADE=TRUE REBOOT=ReallySuppress ADDLOCAL=ALL"

I’m sure the problem is with the double quotes but I can’t seem to get the correct syntax.

Thanks for any help.

Best regards,

Terry

Try the full cmd /k on the command line until it works, then put that in.  You don't need any additional escaping since [Code] uses single quoted strings.

IIRC, this should be the correct syntax (cmd /c or /k is a bit weird with quote parsing):

Hi 

var

  InstallerPath: String;

  Params: String;

  ResultCode: Integer;

begin

  // Den Pfad zur EXE auflösen

  InstallerPath := ExpandConstant('{app}\System Driver\Sentinel System Driver Installer 7.6.1.exe');

  

  // Die Parameter (beachten Sie die doppelten "" für Anführungszeichen innerhalb des Strings)

  Params := '/v ""/passive CONFIRMUPGRADE=TRUE REBOOT=ReallySuppress ADDLOCAL=ALL""';

  // Erst prüfen, ob die Datei existiert

  if FileExists(InstallerPath) then

  begin

    // ShellExec ohne den Umweg über CMD (sauberer)

    if not ShellExec('open', InstallerPath, Params, '', SW_SHOWNORMAL, ewWaitUntilTerminated, ResultCode) then

    begin

      MsgBox('Fehler beim Starten des Installers. Fehlercode: ' + IntToStr(ResultCode), mbError, MB_OK);

    end;

  end

  else

  begin

    MsgBox('Der Installer wurde unter folgendem Pfad nicht gefunden: ' + InstallerPath, mbError, MB_OK);

  end;

end;

Good Day Justyna Stanczyk

You didn't post an actual question, but no, if you're not running this inside {cmd} /k any more then this is over-quoted.  Just use a single set of double-quotes, not two.
