6.0.17 installer broken

Just uninstalled 6.0.7 of SW. Got the 6.0.17 installer, and was confronted with an apparently endless series of dialogs with the famous Microsoft red cross saying "an unknown error occurred when attempting to install [various parts of texlive]". Had to kill the InstallTeX process to stop this. After cleaning up the mess ran the sw6 installer in administrator mode with texlive directory deleted in advance: same problem. Also, the installer did not detect my working inkscape installation.

This is NOT the texlive installer's problem. I went to the location I noticed the texlive installer was unpacked to by the sw6 installer, a .tex folder inside my home folder, and found the installer there and ran it from there with no problems.
