Hi Brett,

Try the FindExecutable function in the SHELL32. Here's the declaration:

DECLARE INTEGER FindExecutable IN Shell32;
  STRING @lpfile, STRING @lpdirectory, STRING @lpbuffer
* lcfile is the file you want to find the executable for
lcdir = JUSTPATH(lcfile)
lcbuffer = SPACE(260)
lnresult = FindExecutable(@lcfile, @lcdir, @lcbuffer)
IF lnresult > 31
  lnpt = AT(CHR(0), lcbuffer)
  lcexecutable = LEFT(lcbuffer, lnpt - 1)
ENDIF
