PowerShell Script after install

Question

Newbie question: I would like to run a powershell script (.ps1) at the end of the inno-setup install. Can anyone give me a tip on where to put this? I want the user prompted to be asked if he wants to run this script.

Oh yes, what this script does is run netsh.exe to open up a port, the script is clever and it grabs Env:username and Env:userdomain from the current context. Would the context be the admin who is running the setup? or would it be the original user that ran the setup.exe?

Answer 1

Another way is to run the script using the ShellExec from the code.

[Files]
Source: "yourPowershell.ps1"; DestDir: "{app}"; Flags: overwritereadonly replacesameversion promptifolder;

[Tasks]
Name: "runpowershell"; Description: "Do you want to run Powershell script?"

[Code]

procedure CurStepChanged(CurStep: TSetupStep);
var
  ErrorCode: Integer;
  ReturnCode: Boolean;
begin
  if CurStep = ssPostInstall then begin

    if(IsTaskSelected('runpowershell')) then begin
      ExtractTemporaryFile('yourPowershell.ps1');
      ReturnCode := ShellExec('open', '"PowerShell"', ExpandConstant(' -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile -WindowStyle Hidden  -File "{tmp}\YourPowershell.ps1"'), '', SW_SHOWNORMAL, ewWaitUntilTerminated, ErrorCode);

    if (ReturnCode = False) then
        MsgBox('Message about problem. Error code: ' + IntToStr(ErrorCode) + ' ' + SysErrorMessage(ErrorCode), mbInformation, MB_OK);

  end;
end;

[Run]
.....; Description: Run Script; Flags: postinstall

(See the help for more details.) By default this will display a checkbox and run under the original user's context (although it depends a bit on how the installer is run).

You might want to reconsider this approach, though; if you are performing a machine-wide install then you should probably open the port machine-wide too. You can do this with pure Inno code calling WinAPIs -- no powershell required. (Which is a good thing, because it might not be installed.)

Alternatively if you want to keep it a per-user setting you should consider making your application prompt the user for a decision on first run. After all, why give an option to only one of the many possible users of your app?
