Inno Setup: Ask for reboot after uninstall

 https://stackoverflow.com/questions/36497580/inno-setup-ask-for-reboot-after-uninstall

 

Use UninstallNeedRestart event function:

function UninstallNeedRestart(): Boolean;
begin
  Result := True;
end;

It makes uninstaller ask for reboot at the end.

 

Note that you cannot combine this with the AlwaysRestart directive.
