I had a bit of a rant earlier about the Windows Live unified installer. Today I came across Long's post about how the installer works and Rafael's x64 pain. Rafael's post lead me to do a search for the Windows Live Writer installation name of Install_{1F973A7F-3FE4-4D11-A9A2-E869C2899A7D}.msi. This great post came up.
Problem solved.
