[Setup] AppName=MyApp AppVerName=1.2.3 AppPublisher=MyAppCo AppPublisherURL=http://www.MyApp.com AppSupportURL=http://www.MyApp.com AppUpdatesURL=http://www.MyApp.com DefaultDirName={pf}\MyApp.1 AllowNoIcons=yes OutputBaseFilename=SetupMyApp1.2.3 OutputDir=M:\RAD\MyAppCo\MyApp1\MyBuilds\_2JK18G30M\exe UsePreviousAppDir=yes Compression=lzma/max VersionInfoVersion=5.2.31 SolidCompression=yes CreateUninstallRegKey=no DirExistsWarning=noThe problem is that it always wants to run the setup in c:\program files\myapp.1 directory, even when I run the same SetupMyApp1.2.3.exe twice. With some other setups I've built with older versions of Inno there was no problem of this kind, at least not that I remember.
