Not reliably. You can chaeck the HTTP_USER_AGENT server variable, but that
will only work on IE.

You'll get something like:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.1.4322)

There isn't a good cross-browser solution as far as i know, short of using
like an applet or something *shrug*.

Only if the client is using Internet Explorer 5.01 or higher.

As Karl indicated.... but more over, Why?
Are you trying to run an app off the client or are you just trying to check
to tell them to install it for another reason?

languagpack.... (97 Mo with Msde)

The .Net Framework *requires* IE 5.01, or later, for its installation.
It's one of its *system requirements*.

See http://msdn.microsoft.com/netframework/technologyinfo/sysreqs/default.aspx

It's quite easy to detect whether the .Net Framework is installed or not,
and which version is installed, if you're running IE 5.01 or later.

There's code to do it here :

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetdep/html/useragent.asp

Since only IE inserts the CLR version in its userAgent, and other browsers don't,
this method will only work for IE browsers.
