Currently my batch file is in [Run] section. I need my batch file to execute before the [Files] section. Is there a way to do this in Inno Setup? Currently the [Run] section always execute after [Files] section.

[Run]
Filename: "C:\Users\Scripts\Install\Install.bat"; \
    Parameters: {code:GetDatabaseName}  
[Files]
Source: "C:\Users\MyApp\*"; DestDir: "\\MyServer\MyApp"; \
    Flags: recursesubdirs createallsubdirs
If it needs to be done at the beginning of the setup, use Exec() in the PrepareToInstall() or CurStepChanged(ssInstall) event functions.
These are both after the user has said "go ahead, install" but before anything else.
PrepareToInstall() also allows you to cancel the install with a nice warning.
If the file needs to be extracted from the setup first, then you can preceed it with ExtractTemporaryFile()
   ResultCode: integer;
begin
   Exec(ExpandConstant('{app}\serviceDeployment\unInstallService.bat'), '', '', SW_SHOW, ewWaitUntilTerminated, ResultCode)
this code always returns an empty string, which tells the setup to continue.
In case you want to stop setup (in some error cases) you need to return a non empty string and it will be displayed to the user (and setup will be stopped).
In order to return an error string add this line in PrepareToInstall's:
Result := 'Your Error Description';
                Well, then would be fair to show how to handle error when Exec fails, or when the executed target returns an error (in this case a batch script returning certain ERRORLEVEL).

                Exec is boolean. so you can check whether it true or false. and ResultCode contains the error code.         if not Exec(.........) then         begin             Result := 'Your Error Description';          end

You can use the InitializeSetup event + some pascal scripting.
See; How to run a file before setup with Inno Setup
Not mentioned in that example; to get the file from the installer you would use ExtractTemporaryFile('your.bat') then Exec(ExpandConstant('{tmp}\your.bat ... to run it.
