Error installing .Net 1.1 ‘Error: internal error 2709 feature GUID for use by Cartman’

I recently rebuilt a dev machine and was trying to install .Net 1.1 and got the following error:
Error: internal error 2709 feature GUID for use by Cartman

It apparently happens when something goes wrong or you have an aborted installation of .Net 1.1 framework.

The fix for this can be downloaded from this address: http://astebner.sts.winisp.net/Tools/dotnetfx_cleanup_tool.zip

Just run the tool and it cleans up everything, my install then proceded flawlessly.
