Delphi can't find ShellBrowser's DCU files

Question / Problem

I got errors saying that the .dcu files of ShellBrowser units could not be located. I tried re-installing the package, but I`m still getting errors. What is wrong and how do I fix it?

Answer / Solution

If Delphi says that DCU files are missing, please check if the appropriate .PAS or .DCU are on your disk. If so, please check in the Delphi Options if these paths are included in the Library Paths.

If you verified that both is conditions are true, then there is most likely a problem with your Delphi installation.
