The "ltfly" is missing a lisp command, but you can type it into AutoCAd on the command line, then run the routine.

1. Load the lisp routine.
2. type "(vl-load-com)"
3. type "ltfly"

What AutoCAD version are you using?
 
(vl-load-com) is of course included in the LTfly code.

Autocad 2006, 2009 and Civil 3D 2009

And it doesn't work in either of them? Strange. At least the 2009 versions should work fine.

Just to be sure:
You perform [CMD]APPLOAD[/CMD] of LTFLY.VLX, start LTFLY, enter "something" and it terminates with the error?

I can image only a single reason why this wouldn't work - a missing or damaged VL.ARX (a standard AutoCAD component). Please start APPLOAD and check the list of loaded applications. Is VL.ARX listed? If not, can you try to load it with the ARX command?

Giving up. And I thought I know LISP quite well...
 
It looks like that the VLisp ActiveX support is missing (VL.ARX, vl-load-com) but both are there in fact. What is the _VERNUM of your AutoCAD (type "_VERNUM")? Are any other add-on applications running?

If user enters a style name not in the drawing, could this error occur?

Posted By: Vladimir Michl

No, LTfly just uses the current style. And the error message points clearly to a missing Lisp-ActiveX component.
 
One more thing - is the AutoCAD version running in a proper operating system? I mean - no twiddling with unsupported 32/64-bit combinations, no virtual machines, no Win95 boxes?
