http://support.microsoft.com/kb/976982
=====================
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
http://support.microsoft.com/kb/318785
Step #2 => Now see Resolution Method 2 in this related KB article:
http://support.microsoft.com/kb/923100
After running the .NET Framework Cleanup Tool, reinstall 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/archi...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.
