Correction!
I was wrong. Microsoft Visual c++ 2013 is installed on this computer.
It got installed the first time I tried to install
postgresql-9.4-beta2. I do not see any of the Microsoft log files for
2013 that I see each time postgresql installs, checks, or updates
Microsoft Visual c++ 2010.
I can try uninstalling Microsoft Visual c++ 2013 before making another
attempt to install postgresql-9.4-beta2.
Thanks,
