List Fields contains several common modules which needs to be so-called registered in Windows. This means that the components are registered in the Registry with it's information, and thus made available to all other applications in Windows that would like to use their functions and features.
In order to register functions in Windows, ensure that the files are placed in the correct directory. Read more about that here. Then open an command prompt (CMD.EXE from the Start->Run ...menu) and locate the system directory with the change directory command CHDIR (or CD for short). This can be done like this:
CD \Windows\System32
When in the system directory, issue the following command:
REGSVR32 <name of file to register>
For example:
REGSVR32 DXDBGRID.DLL
When enter is pressed, you should after a short while see a confirmation message of a successful registration. Do this for all the system files that has "This file needs to be registered in Windows" here.
You may also uninstall - or un-register the component by issuing the -u parameter, such as:
REGSVR32 -u DXDBGRID.DLL
