I gave it a try .. cleaned my registry and ran a utility .. reinstalled but still i got the same error message

There is one more possibility. Your iPAQ may be missing the required GAPI library, depending upon how old the device is and which version of Windows mobile you're running. See if your system contains the file gx.dll. If you find it on your iPAQ, try copying it into the Fish Tycoon and Plant Tycoon folders.

I did a search for gx.dll .. it was not on the device

You can download it from this post. Make sure that you put a copy into each game's folder (as advised by Kieren in the post immediately following Arthur's).

I Downloaded it from microsoft =) And it works like a charm .. thank you Very much! .. you made my wife and I very happy!!! =)
