UT Database Schema Creation doesn't work

Problem:

The execution of the UT Database Schema Creation Tool is not possible. There is neither a response from the application, nor any error message. In the related log files error messages are available. Following error messages are known.

Component 'MSCOMCTL.OCX' or one of its dependencies not correctly registered: a file is missing or invalid
Component 'comdlg32.ocx' or one of its dependencies not correctly registered: a file is missing or invalid
Component 'RICHTX32.OCX' or one of its dependencies not correctly registered: a file is missing or invalid

Cause:

In some cases it was necessary to register a type library. The registering depends on the used operating system. In the command shell it has to be moved to the directory, where the regtlib.exe or regtlibv12.exe is located. Normally this is

C:\Windows\Microsoft.NET\Framework\v2.0.50727\ or
C:\Windows\Microsoft.NET\Framework\v4.0.30319\.

regtlib msdatsrc.tlb or regtlibv12 msdatsrc.tlb
