This issue can occur if the Microsoft .NET Framework 1.0 component which has
been
installed on your computer is corrupted.
You may want to try using the Windows Installer Cleanup Utility to remove
Microsoft
.NET Framework components. Then try to install Microsoft .NET Framework 1.1.
1. You can download the Windows Installer Cleanup Utility, msicuu2.exe from
the following link.
<<http://download.microsoft.com/download/E/9/D/E9D80355-7AB4-45B8-80E8-983A4
8D5E1BD/
msicuu2.exe>>
2. Open it, we can see the msicuu2.exe file. Double click msicuu2.exe to
install
the Windows Installer Cleanup Utility.
3. After installing it, please go to the Start menu => All Programs and find
the
Windows Installer Clean Up item.
4. Remove any items that are related to Microsoft .NET Framework (including
Microsoft .NET Framework 1.0 and 1.1) in the Windows Installer Clean Up
window.
5. Attempt to reinstall Microsoft .Net Framework 1.1.
If it still fails, in addition to running the Windows Installer Cleanup
Utility, you may also need to delete the version folder under the following
directory:
%SystemRoot%\Microsoft.NET\Framework\v1.1.4322
I hope this helps!!

Post by KevinI also have this error when I try to resintall my .net framework 1.1. It
won't allow me to delete mscoree.dll during the installation when the error
occurs. If I stop the installation, installation will rollback including
deleting mscoree.dll. I cannot install .net framework 1.1 due to this error.
Please help?

Hi,
I am trying to re-install the .Net Framework 1.1 and I get this error
message on the installation (The main dialogue says it is Registering
System.EnterpriseServices.dll at the time of failure).
An exception 'System.NullReferenceException' has occurred in RegSvcs.
Has anyone come across this/got a solution?
Thanks in advance,
Stu

Had originally installed Framework 1.1 SP1 - this is a reinstallation of
the
framework after the old one was removed.
