PostgreSQL version: 9.0.0.
Operating system: Windows 7, 64 bit
Description: install failure
Details:
I executed postgresql-9.0.0-1-windows_x64.exe
It died with a message:
"An error occured executing VC++ runtime installer."
I had similar problems with version 8. People gave me various things to
try. None of it worked. I gave up on PostgresSQL. I decided to try again
with v 9.0.0.
I would really like it you stopped using this flaky installer.
