Downloaded the installer and tried to run it. Accepted the license agreement. First time it spent some time downloading the Microsot Visual C++ redistributable. Then it stopped and displayed a panel saying that Project Cooper failed to install.
When I try again, after accepting the license agreement it terminates very quickly with the same message.
I am located in the UK and am running Windows Vista ServicePack 2 in a machine with 3GB RAM and 150GB of free disk space.
