MS .NET Framework 3.5 sp1 shows up in programs list with no "size"shown and won't let me reinstall

Had a glitch with and audio app SoundForge 8 and want to reinstall.
This requires installation of .NET framework 1 and service pack. .NET
Framework 1 will install but not the service pack. I used Revo
uninstaller to remove all versions of net framework to start over and
think this may have caused a problem.

I notice that in the programs list .NET Framework 3.5 sp1 is showing
up (but no net 3.5) but with no "Size" indication and the system won't
let me uninstall it. I get the sense this is related to my install
issues

How do I get rid of this "ghost" install of .NET Framework 3.5 sp1?

Running XP Pro SP2.

Below is an error log that was generated when attempting to install
3.5.

Thanks for all assistance.
