I tried everything, but finally got the install to work after disabling windows security.
I uninstalled the old version and can't get the new one to install (5432) ... the installer runs for about 40 minutes and goes nowhere. Finally, after cancelling the installation I get the following error -- "Setup Error Bootstrapper.cpp:886:fatal error during installation." If this doesn't work, is there a download location for the older version? thanks folks ...
