My .NET 2.0 installation...

....is not being recognized by applications on my system. I use Windows XP
Home Edition SP2 with all patches and updates.
I have .NET 1.1 on my system and applications for .NET 1.1 work great. Just
the upgraded or new applications don't "see" the .NET 2.0 installed.

I have tried uninstalling / reinstalling both the applications and .NET 2.0
several times. This is not helping. (Uninstalled applications, uninstalled
..NET 2.0, reinstalled .NET 2.0, reinstalled applications. With a generous
amount of reboots inbetween each step.)

I have also tried to uninstall everthing to include Windows Installer 3.1 v2
(3.1.4000.2435) and then reinstall everything after a thorough disk clean,
check, and defrag. And still .NET 2.0 is still not working.

Am I missing something? Could there be something else going on here that
will allow .NET 1.1 applications to install correctly but not .NET 2.0?

Then how did you uninstall 2.0 if you don't "see" it installed?

I can see .Net 2.0 in add/remove programs. And It will uninstall with no
errors. It also installs with no errors.

Just my applications won't see it.

You need to explain what you mean by your "applications won't see it". What
happens when you start your application?

I'm just talking about two of the applications as an example. Other
applications have different problems.

Application #1 uses file services that were programmed using .Net 2.0.
Those file services are not installed or do not show up as installed because
they rely on .Net 2.0 to function. Any module for application #1 that relies
on the file services or .Net 2.0 fails to load when application is started.

Application #2 will not install because it says that I need .Net 2.0
installed prior to its installation. When I follow the directions of
uninstalling .Net 2.0 and using it's bundled version of .Net 2.0 for the
installation, the install program chokes when it starts to install the
application saying that .Net 2.0 (the one it just installed) is not installed
and that I need to install it.

Because of the total number of programs (5) all referring directly or
indirectly to the absence of .Net 2.0, I'm assuming there is something on my
system that is preventing .Net 2.0 from installing correctly. Any suggestions?

Thanks for your time in trying to help me.

Have you tried to xcopy the application after installing the .Net framework
manually? Are you using the setup and deployment that comes with VS2005?
Perhaps part of the problem is the installation aspect of the software. Is
the complete application written in 2.0?

The program with the file services was upgraded to .Net2.0 completely. Other
people that use that program have no problems what so ever with it. Only me
apparently.

SP,
After some work, here's what I think is happened:
When I first installed .Net 2.0, the installation was corrupted.
When I followed the advice from a program to uninstall .Net 2.0 and install
the bundled version, the uninstall process could not fully uninstall the
corrupted version of .NET 2.0.
The new install of .Net 2.0 would not fix bad registry enteries left over
from the previous uninstall. Programs would read those bad entries which
still pointed at the uninstalled .Net 2.0. This left .Net 2.0 showing up in
add/remove programs, but applications not "seeing" it. I have no real way of
proving this theory now.
My solution:
Save all data files.
Format C: drive.
Fresh Install of Windows XP. Updated to SP2 with all patches and drivers.
Fresh install of .Net 2.0
Fresh install of all my troubled programs.
Guess what? It all works good now. Restored my data and I'm up and running.
Thanks for your help.
