I'm storing a preferences file for bundled JavaFX app under user directory, which I create at Runtime using

System.getProperty("user.home")

I want to order InnoSetup to delete that file at uninstall, but I can't find appropriate Inno Constant. Please, advice.

On Windows, user.home maps to %USERPROFILE% environment variable, what is typically C:\Users\username.

There's no equivalent constant for that in Inno Setup. Probably because you are not supposed to store any files there. You should store your files to C:\Users\username\AppData\Roaming\app (or ...\Local\app). In Inno Setup that is {userappdata}\app (or {localappdata}\app). It Java, you can use System.getenv("APPDATA") (or System.getenv("LOCALAPPDATA")).

Anyway, to answer your question, you can use {%USERPROFILE}.
See also Inno Setup User Home Path.

Also in general, it's a bad idea to try to access a user profile in Inno Setup (un)installer, as the (un)installer can be executed using a different local account (typically Administrator), than the one you are interested in.

This is covered in Installing application for currently logged in user from Inno Setup installer running as Administrator.

  • but how can I get "\Local\app" at Java ? Is this location ok to to access from Inno Uninstaller? Great thanks. – Evgeniy Mishustin Oct 10 '17 at 09:20
  • I do not know Java. But I assume you can use `System.getenv("LOCALAPPDATA")` - But any account-specific folder, including `..\Local\app` has the same problem as described in [Installing application for currently logged in user from Inno Setup installer running as Administrator](https://stackoverflow.com/q/44575666/850848) - but that's a different topic. – Martin Prikryl Oct 10 '17 at 09:22
