    C:\WINNT\Micros oft.NET\Framewo rk directory will have the directories for the
    version you have installed on your machine.
    C:\WINNT\ : for Windows 2000
    C:\Windows for Win XP

    I have 1.0 and 1.1 both installed on my system.
    so i have two dirs,
    v1.0.3705
    v1.1.4322

    HTH,
    Mahesh

        Re: which .NET Framework version is installed?

        Actually, the same happens to be on my PC. Now, when there
        are two versions of .NET Framework, and I run a program which
        uses .NET Framework, which of these will be actually used?

        Background of the question is: I have a program using .NET Framework,
        which terminates by throwing a security exception. Researching
        the web, I found that this may happen due to a bug an release
        1.0 of .NET Framework, and sure enough the README coming with
        the program says that it needs 1.1. Not knowing at that time
        which version I have, I downloaded 1.1 and re-ran the program -
        but still the same exception is thrown.

        Now that I know that the old AND the new versions are present
        on my PC, I suspect that this program still uses the old version.
        How can I verify this? Is there a workaround?
