Help, please. .NET on XP, versions and uninstalls.

[Al Dykes]

My system is XPSP1, recently updated by Microsoft. It's an older
laptop and I'm running out of disk space.

I only installed my first ".NET' app recently, that I know of, and the
app setup pointed me to URLS to get it from. I dodn't pay attion to
sizes.


Now I find I have the following on my system. I know that version x+1
doesn't replace version x.
.NET 2.0 SP1 at 165MB
.NET 3.0 SP1 at 245MB
.NET 3.5 at 25MB


Questions:

- Do these file sizes indicate that I have a SDK kit where all I need
is a RTK and how much space would I save by just installing the RTK?

- How can I tell which apps on my machine are calling which versions
of .NET?

- I've uninstalled the only software I know of that requires .NET and
it still won't let me uninstall it. Googling for "uninstall .NET"
comes up with all sorts of pages for irrelevant cases such as beta
version, etc. It there a page about uninstall that applies to me?

- What are URLS for find each version as a RTK?

Thanks

Firstly, you have only one version (and the latest version) of .NET
framework installed. That is .NET3.5, which is something built on top of
..NET3.0SP1, which in turn is something built on top of .NET2.0.

Secendly, the size showed in "Add/Remove programs" window may not be the
actual package size. In the regards of .NET framework, the size showed there
varies depending on OS (XP, Server, VISTA...).

To see if it is RTK plus full SDK (which you do not need to save disk
space), you can simply see if you have "Microsoft .NET Framework SDK v2.0"
listed in "Start->Programs". If no, you likely have RTK, rather than SDK.

Thanks, I'm happy to hear that 3.5 replaces 2.0, and 3.0. Others have
told me that I need all versions. I can believe that Control Panel
doesn't report disk space accurately. It appears that I don't have
the SDK.


I believe that only two minor apps need .NET and I've uninstalled
them.

Is there any way to tell which apps on my machine need .NET and which
versions?

Is there a cookbook way to uninstall .NET? When I try to uninstall, I
get a "can't uninstall msg and a search of the MS KB shows
complications but for versions I don't have.

No, What I actually meant is that although you see 3 version of .NET
(2.0SP1, 3.0SP1 and 3.5), you actually is having full 3.5. You CANNOT not
remove either 2.0SP1 or 3.0SP1 to leave 3.5 still working. All the three
must be there. If you use VISTA, you will not see either .NET2.0 or .NET3.0
in the "Add/remove program" window, because they are part of OS.

OK. How do I remove them all?

Do you need SP2 for Win XP installed to install the .Net 2.0 & 3.x versions.
The OP reports his system as a WinXP SP1 system

Right click "My Computer" and choose "Properties" and tell us what that
reports.

It's SP2, Thanks for catching that.

I was able to uninstall .NET 3.5 (the latest) after uninstalling the
two apps that I know use .NET. I'm going to live with the system for
a few days to see if anything broke. Then I'll try to ininstall 2.0
