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 this related KB article:
After running the .NET Framework Cleanup Tool (not the Windows Installer
Cleanup utility), 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:

ALL of it as well as the related page
before using the .NET
Framework Cleanup Tool.
