I got UltraEdit-32 (version 10.2.3.0). Besides the normal exe their is a UltraCompare Lite exe (ucl.exe) (version 1.0.0.1). when I try to run ucl (>ucl.exe FILE1 FILE2 ) I get flash of the ucl screen, but that is all (next screen refresh the window is already gone).
Any idea what i do wrong?

UCL can only be run from within Ultraedit (File - Compare Files). If you want to use command line mode you'll need to install UC Pro.

Cheers...
