I'm also using MUI2.!define MULTIUSER_INSTALLMODE_INSTDIR "MyApp\MyVersion"
I find that when the user changes the default installation directory, the "MyVersion" part is not automatically appended to the directory they choose. I've read elsewhere that that's typically handled by the InstallDir command, but MultiUser hides all that.
How do I get the auto-append feature back for user-selected install directories?
