.NET Framework 1.1 Service Pack 1 fails to Install



Using Windows XP Home SP3

..NET Framework 1.1 Service Pack 1 always fails to Install. I have tried
everything in KB 953297 and 922377 including the cleaner that removes all
versions for .NET Framework.

I have emptied the Software Distribution folder and it still fails. Anti
Virus is off as is the firewall.

I'm looking for something else to try

Hi, Terry. I'm sorry I don't know why you're having a problem with the .Net Framework installation but are you trying to run a program that requires .Net Framework 1.1 SP1? I believe it's pretty much outdated and rarely needed if at all. I've gotten away with only having .Net Framework 2.0 (SP2) installed.


OK try to download a fullfile version from here and then install it when you
are offline.

I seriously think that you may not need this update but you haven't told us
what applications you are using that requires version 1.1.


The above link has everything you need for version 1.1. Have you installed
version 3.5 SP1? all modern applications use 3.5 SP1 or anything that is
bundled with it i.e. version 2.0 onwards.

When installing updates using Windows update or Microsoft Update you may
receive Error 0x643 or 0x80070643 (23 Oct-09)


Step #1 => Before doing anything else, write down what .NET Framework
versions are currently installed:

How to determine which versions of the .NET Framework are installed and
whether service packs have been applied

Step #2 => Now see Resolution Method 2 in...

When you try to install an update for the .NET Framework 1.0, 1.1, 2.0, 3.0,
or 3.5, you may receive Windows Update error code "0x643" or Windows
Installer error code "1603" (ignore the title, if need be)

After running the appropriate/needed tool, (re)install all .NET Framework
versions (but only the ones you wrote down in #1 above) manually using the
download links on the page then run Windows Update manually to install
security updates for same.

NB: If you remove .NET Framework 3.5 SP1 using the tool, reinstalling .NET
Framework 3.5 will also install .Net Framework 2.0 SP2 and 3.0 SP2; then
Windows Update will offer .NET Framework 3.5 SP1.

IMPORTANT! => If you remove .NET Framework 3.5 SP1, reinstall your .NET
Framework versions in the following order:

1. .Net Framework 3.5, then...
2. .Net Framework 1.1, then...
3. .Net Framework 1.1 SP1

NB: KB923100 references this page:
http://blogs.msdn.com/astebner/archive/2006/05/30/611355.aspx. Please read
ALL of it as well as the related page
http://blogs.msdn.com/astebner/pages/8904493.aspx before using the .NET
Framework Cleanup Tool.

Step #3 => Check-in at Windows Update and install any critical security
updates offered.


Peter, thanks for the help

I followed all the directions, again. This time I down loaded Framework 1.1
SP 1 from Microsoft Downloads and installed it just fine, no error.

Re booted and turned on Automatic Updates, Under High Priorty Net Framework
1.1 SP1 shows up again I did not try to re install. Waiting to hear if I



No you don't need to install it. the reason it appears as high priority is
because it is cached on your SoftwareDistribution folder. You can delete
everything from this folder and you won't see a sausage again. To delete
everything from that folder, you need to stop the Windows Automatic Update
service. The easiest way is to boot in SAFE mode (pressing F8 when
rebooting until you get black screen with white characters). Then you need
to go here:


Delete everything from this folder and then reboot the system. The fresh
folders will be recreated.
