Inno Setup: How to run an installed batch file programmatically

Question

How to run a bat file in the Code section (procedure DeinitializeSetup)?

As I tried to do:

Exec('"' + installationFolder + '\mysql\db\db.cmd"',
     '"'+ installationFolder +'"', '', SW_SHOW, ewWaitUntilTerminated, ResultCode);

Source and destination parameters are returning to the correct locations.

Answer 1

To execute the batch file, use Exec support function.

There should be no quotes in the Filename parameter of the Exec().

procedure DeinitializeSetup();
var
  InstallationFolder: string;
  ResultCode: Integer;
begin
  InstallationFolder := ExpandConstant('{app}');
  if Exec(InstallationFolder + '\mysql\db\test.bat',
          '"' + InstallationFolder + '"',
          '', SW_SHOW, ewWaitUntilTerminated, ResultCode) then
  begin
    Log('Succeeded running batch file');
  end
    else
  begin
    Log('Failed running batch file');
  end;
end;

If I install a test.bat with this contents:

@echo off
echo This is test
echo The provided installation path is %1
echo Without quotes: %~1
echo The current working directory is:
cd
pause

using:

[Files]
Source: "test.bat"; DestDir: "{app}\mysql\db"

I get this at the end of the installation:
