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

so i have two dirs,
v1.0.3705
v1.1.4322

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?

How to tell EXACTLY what Version and SP of .NET Framework is installed

by: j.b.messina | last post by:

This has not yet been published by Microsoft. It will be published within the next few weeks, mainly because I asked them to. I felt this was information badly needed, and I think this is the best group to share this information. A co-worker and I were able to determine how to tell exactly what version of .NET Framework is installed. We had to do this because we had to manually deploy the MS05-004 Security Bulletin to thousands of...

I thought ASP.NET was always the same version as the installed Framework?

by: PJ6 | last post by:

Just brought up a fresh installation. Installed IIS first, then VS.NET 2003. Now some of the applications I'm downloading complain that the ASP.NET server version is 1.0 and not 1.1. Um... I've checked, here, and it looks like ASP.NET is v1.1. The Framework certainly is. I'm confused??? Paul

Further framework stupidity

Hi there, Please consider this string of events, 'A' being a client and 'B' being me, A) Your application doesn't work.... B) Please insure the correct version of the framework is installed, that being 1.0 needs service pack 3 and 1.1 needs service pack 1.
