Mario,

See: The .NET Framework 2.0 SP1 installation fails on a computer that
has the .NET Framework 2.0 installed and that is running Windows XP,
Windows Server 2003, or Windows 2000
http://support.microsoft.com/kb/951950

If either a registry 'cleaner' and/or a disk cleanup tool have been
used, then you can rectify the installation issue caused by them by
running the Microsoft .NET Framework 2.0 Registration Correction Tool.
