When I copy my Houdini 1.5 engine to my Arena 3 GUI I get a flag that says my "Houdini 15a w32.exe has the wrong extension". I have xp 32bit x86 single core. When I try to load the engine from the GUI it says "can't find engine". This is my first time downloading and trying to install these two applications. Help.
