I need to check if the C: \ SISAUTO, C: \ BASESISAUTO folder exists. If there are folders, create a new one for example C: \ SISAUTO2, C: \ BASESISAUTO2

Follow the code below.

#define MyAppName "SISAUTO - SISTEMA DE AUTOMAÇÃO COMERCIAL"
#define MyAppVersion "7.0.23"
#define MyAppPublisher "SUPPORT INFORMÁTICA"
#define MyAppURL "http://www.support-br.com.br"
#define MyAppExeName "MyProg.exe"

Simple. You will place a [Code] tag. Then create a validation procedure. Now create a method to be fired before the installation: BeforeInstall. Inside the BeforeInstall you will call your validation methods.

Follow the example:

[Files]

Source: {#MyAppDirOut}\Exemplo.exe; DestDir: {#MyAppDirIns}; BeforeInstall: onBeforeInstall;

[Code]

procedure Validar();
begin
  if (DirExists('C:\SISAUTO')) then
    CreateDir('C:\SISAUTO2');
end;

procedure onBeforeInstall();
begin
  Validar;
end;

The methods you need are DirExists and CreateDir . To work with pascal code in inno setup, just put the [Code] tag.

My colleague's previous answer works, but only in Delphi, and I find it interesting that you edit your question too, why it's focused on inno setup.

You can use System.SysUtils DirectoryExists and ForceDirectories to resolve your issue. For example:

if (DirectoryExists(C:\SISAUTO)) then
   ForceDirectories(C:\SISAUTO2);

Hope it helps. Hugs!
