Hi VFP Experts ~~

I use the code to check AutoCAD installed in computer or not.

If (File("c:\Program Files\AutoCAD R14\acad.exe");
		Or File("c:\Program Files\AutoCAD LT 2000\aclt.exe");
		Or File("c:\Program Files\AutoCAD LT 2006\acLT.exe"))
		
	MESSAGEBOX("YES")
ELSE
	MESSAGEBOX("NO")
ENDIF 

Is there smart way to check it?
I don't want to key all version in code.

Thanks in advance.
