Hi,

You install a .NET 2.0 winforms application on a machine that doesn't have
the 2.0 redistributables and then run it. How do you elegantly detect that
and warn your users? Any way to avoid ugly uncontrollable error boxes?

Thanks
Ron

That's kind of a vicious circle! If the .Net Framework 2.0 is not
installed, your program will not run anyway, so it cannot detect if the
framework is there. You might be able to create some sort of launcher
app in C++ native code that can check for the framework and if present,
it launches the app.
 
Yeah, i thought about it. So assuming I am creating a typical Win32 app
that'll launch the .NET executable, what do I look for in order to make sure
the .NET 2.0 is properly installed? any magical registry element I can refer
to? a file somewhere? what would be the most reliale check?

Your installer should notice that a requirement for your application is
not fulfilled on the system and either refuse to install the application
or install the .NET Framework 2 before installing the application.
