PostgreSQL version: 9.0
Operating system: Windows 7
Description: Add-on installation error.
Details:

Of all the lists, this seems to be be the best place to file this. This
report is not a bug with PostgreSQL; it is a problem with the installer. In
searching the archives, this problem does not appear to have been reported
yet. I apologize if I've submitted this to the wrong list.

When installing postgresql-9.0.3-1-windows_x64.exe on Windows 7, the
installation of PostgreSQL completes successfully. After the installation, I
chose to install the edb_apachephp add-on and the edb_phppgadmin add-on.
When edb_apachephp.exe is run the bitrock_installer_xxx.log file reported
the following (some parts redacted):

----- begin -----

Script output:

Script stderr:
Program ended with an error exit code

Error running C:\Users\XXXXXXXX\AppData\Local\Temp\vcredist_x86.exe "/Q" :
Program ended with an error exit code
----- end -----

To fix this, I located vcredist_x86.exe and ran it as Administrator. I was
given two options: 'Repair' and 'Uninstall'. I chose 'Repair'. Once
vcredist_x86.exe completed, I rebooted. After the reboot, I re-ran
edb_apachephp.exe and it completed successfully.
