Use Inno Setup UI as a self-extractor only - No installation

Question

I use Inno Setup for many \"standard\" installers, but for this task I need to extract a bunch of temp files, run one of them, then remove them and exit the installer (witho

Answer 1

• "Install" the files to {tmp}, instead of using ExtractTemporaryFiles;
• Execute the files extracted to {tmp} from Run section (or use AfterInstall parameter or CurStepChanged to trigger Pascal Script code after files are installed);
• Set Uninstallable to no;
• Set CreateAppDir to no;
• Use [Messages] section to edit the wizard texts that are too installer-centric for your needs.

[Setup]
Uninstallable=no
CreateAppDir=no

[Files]
Source: "dist\*"; DestDir: {tmp}; Flags: recursesubdirs

[Run]
FileName: "{tmp}\MyScript.exe"

Notes:

• The {tmp} folder gets automatically deleted, when the "installer" is closing;
• No need for ignoreversion flag, when installing to new empty folder.
