pgAdmin III 1.12.0 on Windows Server 2003

Hello

I've been using pgAdmin for a few months. It's cool.
But I have troubles with the new version 1.12.0 on Windows Server 2003.

Because of stupid IT management in my company, I'm forced to install pgAdmin III on another Windows machine
and then zip the installed folder (something like C:\Programs\pgAdmin\1.10) and extract the package on that Windows Server machine.
This used to work with 1.10 (including 1.10.5). But it doesn't work with 1.12.0 anymore. At least on Windows Server 2003.
It works on Windows XP.

The error occurs immediately after clicking on the pgadmin3.exe and says something like (it's German on that machine):
The application could not be started because the application configuration is not proper. For troubleshooting, try installing the application again.

The exact version of that Windows Server 2003 machine is (got from Taskmanager->?->Help):
Version 5.2 (Build 3790.srv03_sp2_qfe.100216-1301 : Service Pack 2)

By the way, could you provide zipped packages that don't require installing?
Thanks in advance.

Regards, Patrik
