Create Demo DB: Internal error 1

I installed Adabas 6.4.1 on Windows 7 Professional. The installation went fine, also activating the installation and registering the license file went ok. But the attempt to create the demo DB ( “crdemodb 12” ) results in the following:

C:\Adabas\Adabas\INSTALL>crdemodb 12
Going to create database with ID 12.
Failed to create database with ID 12. Internal error 1.

There is no further information or log available.
Does anyone have an idea what can be wrong?

Thanks and regards,

Solved: It is not sufficient to be an Administrator, it is also required to execute the function as Adminstrator :wink:
