I have noticed that my Windows XP laptop has both version 1.1 and 2.0 of the
.NET framework installed (as well as hotfix KB928366 for version 1.1)
compared with another similar computer that only has version 2.0.

Is having both versions likely to cause me problems?

Can I uninstall version 1.1 safely? I started to uninstall the hotfix but
it gave me a warning that version 2.0 might not work so I stopped.

I'm trying to tidy up my Windows installation because I am having trouble
getting the Adobe website (www.adobe.com) to work properly (e.g. whenever I
try to go to the Flash version test page it times out and getting to other
pages only works sometimes!). The laptop with just version 2.0 of the
framework is able to get to all the adobe web site pages every time. I am
therefore trying to eliminate all differences between the two computers.

Thanks - that is what I wanted to know. As I said in my earlier post i am
trying to diagnose a problem with the Adobe Flash website that affects one
laptop but not the other. The one that is fine only has .NET framework 2.0
in the uninstall propgrams list whereas the one that does not work has both
1.1 and 2.0 so I wondered whether it was possible that this could be the
cause.

May also work on XP, sans the run as admin part ... not sure.

Thanks to all for the advice but unfortunately the computer is running XP not
Vista. The thing that puzzles me is that I have two computers side by side,
both running XP. One always gets into Adobe's site OK, the other (the more
powerful and up-to-date one) often times out even on the home page but always
on certain pages such as the Flash version test. It really is very
confusing!

Anyway, it does not sound as though the .NET issue is likely to be causing
this so I guess I should go and find a more appropriate group to ask for
further advice.

Thanks again for the input I have received here.

It doesn't come into play when browsing a site. I would rather check the
browser settings and the network configuration. It could be also a temporary
server side problem or a firewall issue...

Each version of the .NET framework is desinged to be installed side by side
(ie. an application that runs against 1.1 will use 1.1. and an application
that was created to run with 2.0 will use 2.0)...

Most likely on Vista, which has a problem installing flash (and perhaps
other adobe installers). It is a permissions issue and has to be run as
admin. I am not on a Vista machine right now, or I could find the file and
point him directly to it.

If XP, I am stumped.

Patrice,

Thanks for the advice - I'll leave .NET alone!

I don't think it is the site or router as it is affecting this laptop not
the one next to it.

Hmmm, that gets me thinking . . .
If I am certian that an app on my computer wants to run solely v2.0, then
why should I bother installing the .NET Framework updates that MU tells me
are available?

Hello craigcu,

Because when u try to install something else it could request .NET FW 1.1

:) MS just recommend to install it and forgot it

What's your concerns to have 1.1 installed?

Simply for gaining disk space.
I have spent the last couple days reading past threads and now know better;
that is, leave all the .NET FrameWorks alone and move on.

No. They are essentially different pieces of software.

Sure, but do you have a compelling reason to uninstall it? If so, are you
sure there are no applications you are running that require 1.1 on your
machine (not the other machine).

I doubt it would dink up 2.0. If it did, you should be able to do a repair
install. But, do you really need to uninstall 1.1? I would say no.

Vista? If so, run the installer from the download location (under windows,
forget the folder - google search). You have to run it with admin
permissions. Once you install flash correctly, go to the website and
everything will work correctly.

I would fix the problem rather than play an end run. If this is Vista, there
is a known issue with installation of the Flash player. If you are on Vista,
I would fix that first before performing surgery.
