Running batch file from Inno Setup installer is failing

Question

I'm writing an Inno Setup installer which requires me to do some command prompt work. I need to navigate to a directory, call a batch file with a parameter 'setupDecompWorkspace' and then I'd like to be able to watch it run.

I'm currently doing it this way:

[Run]
Filename:"E:\Project\forge_src\gradlew.bat";Parameters:"/setupDecompWorkspace"

However that isn't working. After this command I would need to do another run of that same batch file with another parameter. As a new approach I tried building my own batch file which did all of this. When I run that batch file from my folder it works fine however Inno Setup is giving an exit code of 1 and refuses to start. It do this I was using:

[Run]
Filename: "E:\Project\forge_src\gradle.bat";

Could anyone point me in the right direction of what I'm doing wrong? I've been able to do it successfully in the command prompt as well as through executing my own batch file but any implementation in Inno Setup is giving me trouble.

Here is the full program:

#define MyAppName "Project"
#define MyAppVersion "1.0"
#define MyAppPublisher "Project"
#define MyAppURL "http://www.project.com/"
#define MyAppExeName "project.exe"

Here is the log file it is creating:

Answer 1

First problem is that you refer to a source file in the [Run] section, instead of the installed file.

Unrelated side-note: You should also not be hard-coding a path to Program Files (x86). Use a {pf}, {pf32}, or even better an {app} constants.

[Files]
Source: "E:\Project\*.*"; DestDir: "{app}"; Flags: recursesubdirs

[Run]
Filename: "{app}\installers\gradle.bat";

---

But if you are actually testing the installer on the same machine you build it, the installer should still find the gradle.bat in the source directory.

In such case the problem will be the with the actual batch file. We cannot help you with that, without seeing its code. General hint is to add some logging to the batch file and inspect that. You can extract the code to a separate batch file (e.g. gradle_internal.bat) and call that from gradle.bat with redirect:

gradle_internal.bat 2>&1 > %TEMP%\gradle.log
