First please always ensure that Delphis Library Path includes the Paths of all the files. You can copy all Files distrbiuted by me as installable into delphi into one directory. The File ahm.inc is the same everywhere and can be replaced.
If you have any other troubles installing any one of the sets please contact me at ahm@global.co.za and I will try to help you out whereever I can.

Thank you, Alexander Mehlhorn
