Palm PCs: Uninstallable Software

I recently bought a Palm m130. While surfing on the Internet I came across some utilities that I feel would make the interface more user friendly viz "Smallmenu/mallmenuPlus, Programmenu21" and others. These applications are supposed to provide among other things, a cascading menu with icons which I really fancy. I downloaded them and proceeded to install them. However, they could not be installed because of a missing "CeAppMgr.exe" file. I do not know what this file is and where to get it. I have been to "Tillanosoft" home page but could not find any help. Could anyone please help?
