You can check which versions of FW are installed by creating small stubs
(.exe) in either version of FW, which call e.g. Environment.Version.
Try to start them. One of them will fail. If both succeed - you have both
versions.
E.g.
static void Main() {
Console.WriteLine("Running under framework {0}",Environment.Version);
}
Create one exe in FW 1.0, another in 1.1. Run both and check output during
installation.
I think presence of directories or registry keys doesn't mean much. It is
unreliable.
