If you encounter any problems during installation, please check the
logfile that is created in /tmp on Linux or Mac OS X or %TEMP% on
Windows. The file will be called install-postgresql.log. The logfile
may contain the superuser password you specified during the
installation, which should be replaced before sharing the log with
anyone.
 If you are unable to resolve the problem having reviewed the logfile,
please search the EnterpriseDB forums as well as your favourite search
engine for a solution.
If you still cannot resolve the issue, please post details of the
problem, along with system details and any appropriate parts of the
installation logfile to the installer forum.

Script output:
Error de entrada: No existe ningún motor de secuencia de comandos para la extensión de archivo ".vbs".
Input Error: No script command engine for ".vbs" file extension exists. (Yes, I got a spanish localized windows)

Script stderr:
Program ended with an error exit code

Unknown error while running cscript //NoLogo "C:\Documents and Settings\Name\Configuración local\Temp\prerun_checks.vbs"

Running from cmd 'cscript //NoLogo "C:\Doc...\prerun_checks.vbs"' returns 'The scripting host appears to be functional.'

... Checks the program configured to open vbs files ... (Notepad ++)
... Changes to default ... (Microsoft (R) Windows Based Script Host)
... Installer works ... (shoots computer (after making appropriate db backups))

All right, no more problems on my end. Thank you for your swift response and pointing me to the right direction.
