7u6 b18 install fails
Ran the installer and part way through it says:
Error 172. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.
This was with the 32-bit installer for Windows, running on Windows 7 64-bit, with a previous build of 7u6 already installed (I answered Yes when the installer claimed it was already installed and asked if I would like to re-install)
It happened as the installer said "Extracting Installer" presumably the JRE installer.
