There is no file missing problem or software bug. Our software comes with all necessary files.
The problem's nature is that the software installer could not register one of software components on your system.
In the other words registering of component is nothing else that writing component keys into a system registry.
In your case something else was preventing to do that.
To solve this problem
You can register a component manually executing the following command from the command prompt
How to do:
Go to Windows Task Bar, from the Start menu select Run, this window should be opened for you

This window above is showing you a sample command line, which allow to register beegdo10.ocx component.

In the text box named Open enter or paste command lines from a list below. Depends on a Windows system that you are using, you should change in the Command line: System32 with System when you have Windows 98, SE or ME.
It applies only to those command lines, where component's path is pointing to the Windows system directory.
Those command lines (listed below) are prepared for software that was installed into a default installation folder.
If you have software installed into different directory then you have to change the path.
You can use those commands with all of components and programs, just change the software name if necessary.
Note: actually, you can register the file in many different locations. If registering of file fails, you may try to copy a file to different location like c:\filename.dll and try again.
