>>I am using some of the great functionality of Focus.FLL. It works great on my development machine. When I install my app on some other machines I get an error message "FOCUS.FLL is invalid" when I SET LIBRARY TO. I am also using Foxtools and ComTools with no problems. Only Focus.FLL does not work on some machines. On others it works OK.

Finally found the problem. FOCUS.FLL is dependent on MSVCRT.DLL and it was not installed on the problem machine.
