PostgreSQL installation - error loading modules - postgresql

Question

I haven't been able to re-install PostgreSQL + PostGIS properly on our virtual server.
Installing PostgreSQL the following error occurs about the end of the process:
"A non-fatal error occurred whilst loading database modules. Please check the installation log in C:...\Temp for details."
Here is what the log says:
Loading additional SQL modules...
Executing cscript //NoLogo "C:\Programme\PostgreSQL\9.0\installer\server\loadmodules.vbs" "postgres" "****" "C:\Programme\PostgreSQL\9.0" "C:\Programme\PostgreSQL\9.0\data" 5432
Script exit code: 2
Script output:
Installing the adminpack module in the postgres database...
Executing 'C:\DOKUME~1\Kiesow\LOKALE~1\Temp\rad3C00F.bat'...
Couldn't find the output file...
Failed to install the 'adminpack' module in the 'postgres' database
loadmodules.vbs ran to completion
Script stderr:
Program ended with an error exit code
Error running cscript //NoLogo "C:\Programme\PostgreSQL\9.0\installer\server\loadmodules.vbs" "postgres" "****" "C:\Programme\PostgreSQL\9.0" "C:\Programme\PostgreSQL\9.0\data" 5432 : Program ended with an error exit code
Afterwards installation completes, I can start pgAdmin, log in and create new databases. Everything looks fine until I try to add PostGIS, using the stack builder wizard. Again the installation is almost finished, when:
"Database creation failed."
"Would you like to view the error log " "create_templatepostgis_db_error.txt'?"
This error log doesn't exist. I might ignore the error and create the template db manually, which works. But I cannot use types like 'geometry', so I think, PostGIS is not yet usable.
Maybe anyone of you has got an idea of what I could have done wrong? Any hints? Can anybody help me to interpret the error log?
I use Windows XP, PostgreSQL 9.0 32bit (same with 8.4), PostGIS 1.5.
Postgres 8.3 + PostGIS was installed on this system earlier, but I uninstalled, deleted the data directory and let the installation wizard create a new posgres windows user.
Did a few reboots, too.
And I did choose a locale instead of [Default locale] at Postgres installation.
This is another part of the log I am suspicios of. It is right in the beginning. Maybe this helps:

Answer 1

From a command prompt, run this single command:
C:\Programme\PostgreSQL\9.0\bin\psql.exe -p 5432 -U postgres -W -f C:\Programme\PostgreSQL\9.0\share\contrib\adminpack.sql postgres
Its output may be more informative. Running the above is all the .vbs is doing, incidentally.

Answer 2

The reason for prompting this error message was due to because of localhost is pointing to some other machine.

Answer 3

disable firewall and antivirus and try installing it again.
